When your engine cranks but won't start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). However, the source may also be a mechanical fault (for example, a leaking valve), or faulty components in other systems.

What "crank-no-start" doesn't generally mean is a problem with the starter. If the engine cranks normally, you don't have a starting problem. If it isn't cranking right (the engine rotates slowly or doesn't rotate, or you hear weird noises or nothing when you try to start the engine), check this other practical guide to troubleshooting the starting system.

Whatever you do, avoid cranking the engine repeatedly with the hope that the engine will fire up. You may drain your battery of power and damage the starter motor in the process. Instead, try to use the charge left in your battery to locate the fault.

This guide will first give you six quick things you can check, and then three systems to troubleshoot—the spark, the fuel, the compression—using some simple and quick diagnostics. Then, for more help, you'll see a list of components in related systems that can be associated with a no-start condition.

Six Quick Checks

Check These Possibilities First

When trying to find out why your car doesn't want to start, keep in mind these possibilities.

  1. Fuel. For example, make sure there's actually fuel in the tank.
  2. The computer in modern vehicles monitors and controls a good number of sensors and actuators. Scan your computer memory for trouble codes before you do anything else. Even if the check engine light hasn't come on, you may find a pending code that can guide you in your diagnosis. False input or lack of input from sensors like the crankshaft position sensor (CKP) or camshaft position sensor (CPS) can prevent the engine from starting. Also, a bad throttle position sensor (TPS) may cut off the spark to the cylinders.
  3. Battery. If the engine cranks slowly, you may be dealing with a discharged battery, loose or corroded battery terminals or starting system wires
  4. Starting System. If the engine doesn't crank, or makes an unusual noise when cranking, you may have a starting system problem.
  5. The car's security system may have made an error that disabled the fuel or ignition system, or the chip in the key may have failed. To troubleshoot a built-in security system, consult your car owner's manual or consult with the shop that installed your alarm system.
  6. Check for a blown fuse that may be preventing a circuit from working properly, like the fuel injection or computer system.

Troubleshooting: Spark, Fuel, Compression

To operate efficiently, an internal combustion gasoline engine needs a good spark, the right amount of fuel, and good compression (a healthy mechanical condition). The lack of any of these three things will prevent your engine from starting.

So, the next three sections will list series of steps to help you find out whether your engine is lacking adequate spark, is not getting enough fuel, or has too low compression.

I. Do You Have Spark?

First you want to check that a good spark is reaching the cylinders. You can do this test without a spark tester, but it's better to use one, because a weak spark as well as a missing spark can prevent your engine from starting. If possible, use an adjustable tester so that you can test for 40KV, 30KV and 10KV spark.

  1. Select an easy-to-reach spark plug and unplug the spark plug wire, or coil wire, or coil on plug (COP).
  2. Set the spark tester to 40KV, and plug it in at the end of the spark plug wire or coil wire. Hook the spark tester to engine ground. To ground the tester, use an unpainted bracket or bolt on the engine. NOTE: If you are not using a spark tester, grab the wire with a pair of insulated pliers and place the tip of the wire about half an inch form ground (engine block, bracket, cylinder head). You still need a helper to crank the engine for you. The rest of the test is the same. You'll be able to test for the presence of spark but not its strength.
  3. While watching the spark tester, have an assistant crank the engine.
  4. You should see a bright spark jumping the gap in the spark tester.

If you don't see a spark, repeat the test. This time, adjust the spark tester to 30KV. If still you don't see a spark, repeat the test and set the tester to 10KV. If this time you see a spark or no spark, you have a problem in the ignition system. Consult your vehicle repair manual for your particular model for further diagnosis. Depending on your particular model, you may have a problem with an ignition coil, distributor, ignition module, igniter, or some other related component.

Other Checks You Should Do:

  • On systems with a distributor: Check that the distributor cap isn't loose; inspect the distributor cap for moisture, cracks, carbon traces or some other damage; there could be faulty distributor components.
  • If you haven't replaced the spark plug wires in more than three years, your wires may be worn.
  • Also, check your car owner's manual or vehicle repair manual for the interval schedule for the spark plugs. Your may need to service (gap check and adjustment) or replace the plugs.
  • If you installed new spark plugs and your car refused to start right after, double check that you installed the correct plugs for your vehicle model, and the plugs have the correct gap. Use a wire feeler gauge to check and adjust the gap.

II. Is Fuel Reaching the Cylinders?

After checking for spark, you need to check that the engine is getting fuel.

To Check a Carburetor or Throttle Body Injection (TBI) System:

  1. Take the lid off the air filter box and open the throttle plate (carburetor). On TBI systems, watch the fuel injector.
  2. Ask an assistant to crank the engine and see if fuel is being fed into the unit.
  3. If you don't see fuel being injected, your problem is in the fuel system. Make sure of the following:
  • you have enough fuel in the tank,
  • the fuel pump is working,
  • the fuel filter is not clogged (consult your car owner's manual or repair manual for the service schedule),
  • the fuel pressure regulator is working properly
  • the fuel injectors are not clogged.

To Check a Multiport Fuel Injection System:

  1. First make sure the fuel pump is working. Momentarily remove the fuel filler cap.
  2. Ask an assistant to turn the ignition key to the On position, but don't start the engine.
  3. As your assistant turns the key, listen closely through the filler neck of the fuel tank. You should hear the whirring sound of the fuel pump motor being energized for two or three seconds. If you hear the sound, at least you know the pump is getting power; continue with the next step. Otherwise, you may be dealing with a faulty fuel pump or relay, a blown fuse, an electrical open or another problem in the fuel pump circuit.
  4. Detach the air cleaner assembly from the throttle body.
  5. Open the throttle plate and spray some starting fluid into the throttle body.
  6. Crank the engine.
  7. If the engine still doesn't seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator. Consult your vehicle repair manual, if necessary.
  8. If the incoming fuel line that goes to the fuel injectors has a test port (Schrader valve - a valve similar to the one on your tires), use a small screwdriver to press on the valve. Be ready with a shop rag to catch the fuel.
  9. Turn the ignition key to the On position for two or three seconds and then turn it off. Repeat the step two more times to prime the line with fuel.
  10. Then, press the valve with the screwdriver while catching the fuel with the shop rag. Fuel should squirt out through the valve. Instead, if a dribble of fuel comes out or no fuel, then check for a clogged fuel filter, a bad fuel pump or leaking fuel pressure regulator.
  11. If fuel squirts through the valve, plug a fuel pressure gauge to the test fitting valve and turn the ignition key to the On position and read the gauge. Then have an assistant crank the engine and read the gauge.
  12. Compare your gauge readings to the pressure specification listed in your vehicle repair manual.
  13. If pressure is lower than specification, your problem lies in the fuel system, possibly a faulty fuel pump, clogging fuel filter or bad fuel pressure regulator. Detach the vacuum hose from the top of the fuel pressure regulator. If the line is wet and smells to fuel, replace the fuel pressure regulator.
  14. If pressure is within specifications, you can unplug a fuel injector electrical connector and plug in a nod light to the harness connector (you may loan a set of nod lights from your local auto parts store).
  15. Ask your assistant to crank the engine, while you watch the nod light.
  16. If the nod light flashes while the engine is being cranked, you can at least assume that the injectors are receiving the pulse signal from the computer. If not, you need to check for a blown fuse or bad relay in the fuel injection system, a problem with the computer control, or problems with input sensors (for example the crankshaft or camshaft position sensors). Scan your computer for trouble codes. Refer to the list of related components below.

Some Cars Automatically Shut Off the Fuel Pump After a Crash

Some models, like many Ford vehicles, have a fuel pump switch (inertia switch), that automatically cuts power to the fuel pump when involved in an accident. If your engine refused to start after an accident or after a vehicle struck yours in a parking lot, check for an inertia switch. The switch helps prevent your car catching on fire if an accident occurs. Check your car owner's manual or vehicle repair manual to locate the switch. You can pop the button back in manually.

III. Do You Have Proper Compression?

Compression in the cylinder heats up the air-fuel mixture and helps the spark ignite the mixture so the combustion takes place. During the combustion process, though, there should be no air leaks. Otherwise, the cylinder will have poor combustion, or it will not happen.

The most common source of air (combustion) leak is a jumped timing belt or chain that allows air to escape through a valve; it can also happen because of a burned valve, worn-out compression rings, or a blown head gasket.

A timing belt or chain synchronizes camshaft to crankshaft rotation. After miles of service, it wears down, becomes damaged, or breaks. So car manufacturers suggest replacing a timing belt every five years. A timing chain may have a wider service schedule interval. Replacing the belt or chain at the suggested interval can prevent serious engine mechanical problems. Consult your vehicle repair manual.

On some vehicle models, it is easy to remove the timing cover to check if the belt or chain is still in place. If it is, you may be able to visually inspect the belt or chain condition, and then check that it hasn't jumped. Follow the instructions in your vehicle repair manual.

Likewise, you can check compression pressure using a compression gauge. If you have a gasoline engine, you screw the gauge into a spark plug hole; on diesel engines, screw the gauge in place of a glow plug or injector nozzle. Follow the instructions in your vehicle repair manual.

Gasoline engine compression ranges from 130 to 180 pounds per square inch (psi); diesel engine compression may range from 250 to 400 psi.

Other Components That May Cause a No-Start Condition

Faults in other systems, not just ignition, fuel, or compression problems, can prevent your engine from starting. A system component itself may be faulty, or there may be a problem with its wire connector or harness. You may need to expand your diagnostic procedure to the components below.

Computers in modern vehicles monitor many of these components (usually in emission-related systems) and can set trouble codes when problems arise. So don't forget to scan your computer.

1. EGR

The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting. Other symptoms of a stuck-open EGR valve include rough idle and stalling.

2. Cold Injector

Some vehicle models use a cold-start injector. It operates as a regular injector, but only works when the engine is cold. The injector may have its own thermo switch or may be commanded by the system control module. If either the switch or the computer circuit fails, you may have a hard time starting the engine during cold months. Consult your vehicle repair manual, if necessary.

3. MAP

The manifold absolute pressure (MAP) sensor compares the barometric (atmospheric) pressure to the intake manifold vacuum. When the sensor fails, it can prevent your engine from starting. Not all vehicles use this sensor. Consult your vehicle repair manual.

4. MAF

The mass air flow (MAF) sensor tells the computer the amount (the density) of the air entering the engine. A common MAF problem is dirt or foreign matter blocking the sensing element, preventing the sensor from working. Or the sensor itself may fail after miles of service. You can clean and test the sensor at home.

5. ECT

The computer uses the engine coolant temperature (ECT) sensor to know how much fuel the engine needs and when to enter closed loop operation (that is, when the engine has reached operating temperature). Depending on your particular model, a bad ECT sensor can upset ignition timing, or the operation of the transmission or cooling fan. Consult your vehicle repair manual, if necessary.

6. Canister Vent Valve

The canister vent valve is part of the evaporative emissions control (EVAP) system. The EVAP system temporarily stores harmful fuel vapors into a canister to prevent their release into the atmosphere. When conditions are appropriate, the computer routes the fuel vapors out of the canister through a canister vent valve and into the intake manifold for burning. A faulty valve, though, can prevent the engine from starting. Consult your vehicle repair manual for the procedure to test the valve.

7. TPS

The throttle position sensor (TPS) monitors the position of the throttle valve. It sends a voltage signal to the computer. The computer uses this information to regulate the air-fuel mixture according to engine needs. On some vehicle models, a worn out, failing or bad TPS will prevent your engine from starting at all.

8. Vacuum Leaks

Vacuum leaks are not uncommon, and they are the source of many engine performance problems, including fail to start. Depending on where the fault is located, vacuum leaks can be hard to find. But mayor vacuum leaks that can make the engine hard to start may happen in the power booster vacuum hose, EGR valve, another main vacuum hose or a blown head or intake manifold gasket.

9. Carburetor

If you have an old vehicle model with a carburetor, double check that the fuel level is properly adjusted. If the carburetor is flooded, you'll probably perceive a strong fuel odor under the hood. A little trick you can use is to fully depress the accelerator and try to start the engine. If the engine doesn't start, wait for a few minutes and try again.

When your engine cranks but fails to start, it can be difficult to fix if you don't know where to begin troubleshooting. This guide not only tells you where to start but helps you build your diagnostic strategy. And reminds you of some simple but easy to forget places to look into. So most of the time, using just this guide you'll be able to zero in on the problem.

Questions & Answers

  • My Toyota Mark ll engine cranks but won't turn over. What would be the main cause of this?

    If the engine cranks, it turns over. If you mean the engine cranks but won’t start, then follow the diagnostic procedure in the post. The fuel and ignition system are the most common issues.

  • My Toyota Funcargo just stops while driving and won't start turning over but just not starting. Could it be a bad coil pack?

    It's possible. But you also need to make sure you got fuel pressure. This other post may help:

    https://axleaddict.com/auto-repair/How-to-Test-a-F...

  • My Toyota quantum 2.7i cranks but won't start. I have checked the fuel pump and the spark plugs what should I do?

    Check you have the correct fuel pressure and good spark (use a spark tester). Then scan for possible trouble codes. There could be a problem with a sensor; crankshaft position sensor, camshaft position sensor, or mass airflow sensor can cause this problem in some models.

  • 2006 Sierra 1500 4.3 which cranks, has spark, has the proper fuel to the metering valve and will not fire, just crank. I will be doing a compression, but what are some other things common to these that I should check with my Sierra's engine? It has an EVAP code causing for the fuel cap, but that code has been on for a while.

    Make sure to download trouble codes, possibly pending codes other than the EVAP related one. And you may want to check the fule system. There could be something else triggering the code that might be related here. Other than that, if you've been able to fire up the engine after a hard start, and it runs good, concentrate on the starting system. There could be several causes for this. Check the IV section on this other post, it may help:

    https://axleaddict.com/auto-repair/No-Trouble-Code...

  • I have a 2001 Ford Focus and the battery and alternator are 6 months old. It started just fine. I got maybe 2 miles and an engine light popped on, shut off the car when I tried restarting. It would turn over slowly but wouldn't start. I checked the plug wires and they were covered in oil. Could oily plug wires be preventing my Ford Focus from starting?

    The oil may have fouled the spark plugs and wires. Check for the source of the oil leak and fix it. Check the oil level and add, if necessary. Then clean the spark plugs and wires.

      Make sure the battery is fully charged and therminals are clean and tight. If you hear a solid click when trying to start the engine, maybe the starter is bad. If you hear a series of clicks, probably is not receiving enough voltage. Check the starting circuit:

      My 1997 Dodge Ram 1500 has several times failed to start. The starter turns but the engine won't catch. It only happens when restarting the engine after a brief stop, like running into a store, never first thing in the morning, and after ten minutes or so it will suddenly start fine again. Today it cut off while I was driving and did the same thing.

      The fuel system might be slowly loosing pressure. Try turning the ignition key On, leave it there for a two-three seconds, then turn it off. Repeat three to five times, trying to build system pressure, and then try starting the engine. If it fires up without an issue or much easier, then the problem is in the system. Check system pressure, if necessary, next time it happens. Hope this helps.

      There could be a problem in the ignition system, loose wire or dirty connector, faulty ignition module; or a fault in the fuel system. Next time it doesn't want to start, spray some starting fluid in the throttle valve. If seems to catch while cranking, the problem is in the fuel system; otherwise it could be in the ignition. Hope this helps.

      Check for a spark when the engine doesn't fire. Also, there may be a problem with the starter motor. Usually worn bushings will cause this. Problems with the fuel injectors leaking or internal electrical (coil) fault may cause this as well.

      If you checked for trouble codes and the problem was for a crank sensor, check the connections or the wires; sometimes there's where the problem is. Also, download codes and see if there's still one for the sensor or a pending one that can point to the problem.

      If you still have no spark, you may have a problem with a sensor. Although a faulty crankshaft position sensor can prevent the engine from starting, the fault can be with the circuit. Download trouble codes, even if you don't see the check engine light on. A pending code may give you some direction here. BTW, make sure you have good fuel pressure, not just fuel flow. Hope this helps.

Is there any other cause for this? Again it ran before we took it out of the grain truck and everything is hooked up.

      If you are getting good spark, you might want to check the fuel pressure. A fuel filter is a possibility if you haven't replaced it in more than a year or two.

      If your ignition key is getting stuck, make sure your battery is fully charged and check the wheel lock cylinder.

      I have a 2002 Honda Accord se 2.3L. One morning woke up wouldn’t enter start. Checked timing. Fine. Valve cover gasket and tube seals fine. New spark plugs. Magically got it to star once. Drove it. Idling rough, driving rough. Checked compression in all cylinders.fine. Cleaned contacts on Distributor cap. New spark wires. Currently looking at fuel filter, but it seems fine. Before this incident I replaced catalytic converter and it ran the best since I’ve owned the car. I’m truly stumped? Anyone welcome to take a stab.

      Try rotating the engine manually using a socket, ratchet extension and a breaker bar. Set the transmission to neutral. If it is too tight, try removing the spark plugs, if it still too tight, theres something wrong in the assembly. If it turns without much effort, check for a good spark and fuel pressure.

      Check all the fuses; there could be another blown fuse. Then make sure you got spark, and fuel pressure. These are the most common reasons for a crank-no start issues. If it doesn't crank, check the starter relay and connections to the starter motor and battery terminals. Make sure the battery is fully charged.

      If this is a rebuilt engine, you may need a new starter motor. But you may want to make sure you got a good spark, and fuel compression.

      The problem could be in the emission or fuel system. Maybe this other post can help. Specially, check the first section:

      I have a 1996 Mitsubishi Montero that has been having issues, it will start but sputters out when I press the gas if I left off the gas it seems to pick up power for a couple seconds then stalls out again, after 10 or 15 minutes of this I can finally get her to move and she seems to do fine, till she has say for awhile then same deal all over again, I've checked the throttle body, air filter and changed the fuel pump and fuel strainer, I got in her this morning she started right up...... for about 30 seconds then stalled now she will not start at all. I've tried starting her while pumping the gas but no help, I don't even smell fuel at all. Any ideas where else to check? I've also checked the spark plugs and wires and they are all nice and silver with no signs of fouling.

      The problem could be in the sensor's circuit. Check the wires and connectors. You want to clear the codes as well and see if the code shows up again. On some models, the crankshaft sensor's gap is adjustable. You can also check sensor operation with an AC voltmeter for the signal. You may need your vehicle repair manual to check this.

      Hi :) My 2007 Chevy Malibu quit running one night. I figured the alternator was going out before we left town, so we put a new alternator in. Trying to start the car after that, the starter smoked and turns out, had a short in it. So we put a new starter in as well. The engine cranks, but wont fire up. The computer reading said it was the Crankshaft Sensor. We put a new one in, but its still not firing up, and the computer STILL says its the crankshaft sensor. I have a list of things to check, after reading this awesome article, but thought Id run this by you to see if you had any ideas on what it would be specifically? I appreciate your help!! Thanks

      Hi Todd,

      Seems like a fuel system problem.

      Check if the fuel pump is pressurising the system when you turn the key to the On position. If you check pressure and it came OK, and if the fuel pump relay checked OK, then try this. Turn the igniton key to ON so the lights on the board come on and then turn it off -- repeat the cycle about 6 times and see if the engine starts. If it does check the drain-back valve.

      1999 Dodge Ram 1500 5.9 cranks but no start. Spray starter fluid and runs fine, if I shut it off you won’t start again. Changed cap and rotor, right fuel pressure, ignition coil is getting power all fuses are good and relays, new battery and alternator. Spark plugs and wires wehere changed about 4000 miles ago. Would the wires to the remote starter if there were loose connecting cause it not to start?

      Make sure you're getting good fuel pressure - check the gauge results with specs in the repair manual. Also, check the compression.

      Hi. I have a car Kia sephia 1999 model and a Fuel Injected (FI) car. It cranks but it wont start. We've already checked the spark plugs and replaced it with new one. Replaced fuel pump, charged the battery, buys new fuel filter and air filter, the starter was okay, and its alternator was all fine. I don't know what to do to my car. My head hurts.

      This is usually a fuel system symptom.

      Check fuel pressure. A common fault is an O-ring in the fuel pressure regulator. On some models it's kind of difficult to reach but not impossible. You may need your repair manual to check specs, if necessary.

      Check the fuel injectors and pressure fuel pumps as well.

      Hope this helps.

      Hi MIke

      Check the starting circuit connections and have the starter check. A solenoid can wear out, pit, and collect carbon residue and prevent full current from operating the starter.

      Good luck

      I have a 2007 Pacifica w/ 4L engine w/ 120K miles. I have a brand new full strength battery and the car almost didn't start. There are no unusual sounds that might indicate a starter problem. Also, I have no other signs like check engine light, poor acceleration, rough idling, or lower gas mileage. Any ideas what might be the problem?

      Hi Jennifer

      Check the ignition coil(s) and modules. If there's no spark at all, there might be the fault.

      Good luck

      Hi Allen

      Check for spark first and than check fuel pressure. You can find the specs for your model in your vehicle repair manual.

      Good luck

      Hi JF,

      It won't hurt your engine, but probably you'll need to take care of some items sooner than later, probably the air filter. Usually these scoops have some way to drain water to keep it out of the engine as much as possible.

      Good luck.
