Car Starter Problems? Five Starting-System Inspection Tips
Car starter problems arise unexpectedly and for more than one reason. Whenever there's corroded terminals, loose connections, a bad, worn out or damaged system component, you'll notice. Starting your car becomes more difficult or it simply refuses to start.
Unfortunately, you won't see the source of the problem when all of a sudden the system fails. And repeatedly turning the ignition key, hoping that eventually the engine will fire up when it refuses to start, doesn't always help. Most often, it creates more problems.
Fortunately, common starter system problems happen in predictable places. And you have at your disposal more than one strategy to help you check the system in your car. Whether it is lack of power, a bad electrical connection, or a bad starter component, use these five troubleshooting tips to fire up your engine again.
Begin with one of the most common sources of engine starting problems.
Checking the Battery Voltage
You need to know whether you have enough juice to operate the starter motor by measuring the amount of voltage in your battery using a voltmeter.
- Set your voltmeter to a range higher than battery voltage, like 20 volts on the DC (direct current) voltage scale.
- Turn on the meter and connect the test leads across the battery terminals. Touch the negative lead to the negative (-) post on the battery and the positive lead to the positive (+) post on the battery.
- Turn on your car's headlights.
- Read the display on your meter. Your battery should have between 12.4V (75% charge) and 12.6V (100% charge) to properly operate the starter motor. If there's less than 12.4V, recharge the battery and try to start the engine again.
With a reading of 12.4V or less on a three to four years old battery, it's a good idea to hydrometer-check your battery. The hydrometer is a simple tool that lets you know the state of charge and health of your battery. So you'll know whether one or more cells have failed. Buy an inexpensive hydrometer online or at most auto parts stores. Then check this article on troubleshooting a car battery using a hydrometer.
Common Sources of Starter System Problems
- Loose electrical connections in the starting system
- Dirty connections
- Corroded battery terminals
- Worn out or failed starter system parts
Inspecting Cables and Wires
Corrosion around battery terminals prevents electrical flow. This is a common problem on a battery or starter system that hasn't received much attention. If you notice a layer of corrosion around one or both battery terminals, clean them with a solution of baking soda and warm water.
- Mix 8 ounces of warm water for 1 tablespoon of baking soda in a small container.
- Thoroughly mix the solution.
- Disconnect the terminals from the battery and apply the solution to the terminals and battery posts using a soft brush.
- Clean the battery top with the solution as well to remove dirt and acid, which drains battery power, but don't let the cleaning solution seep under the filler caps.
- Remove the caps from the top of the battery and check the electrolyte level. The electrolyte should reach the bottom of the filler rings. If necessary, add distilled water to bring the electrolyte to the correct level.
- Check the tray where the battery sits and clean it as well.
- Reconnect the terminals and try starting the engine again.
Inspecting the Starter Solenoid
Check the connections at the starter solenoid (the small cylinder on top of the starter) or starter relay. Most Ford vehicles use a remote starter relay instead of a solenoid. The positive (red) battery cable connects directly to the solenoid or starter relay. Can't find the relay? Consult the vehicle repair manual for your particular car make and model.
If the solenoid or relay fails, the car won't start:
- To quickly check the solenoid, disable the starting system by disconnecting the thick wire from the center of the distributor cap or by removing the fuel pump fuse — consult your vehicle repair manual to locate the fuse, if necessary. This will prevent the engine from accidentally starting as you check the solenoid or starter relay.
- If you disconnected the wire from the distributor, ground it to a bolt or unpainted metal bracket on the engine block using a jumper wire.
- Ask an assistant to try starting the engine as you listen for any sounds coming from the starter solenoid or relay. If you hear a solid and loud click, it means the electrical current is reaching the solenoid and it's properly working. If you hear a weak click or chattering sound, check the wires connected to the starter solenoid or relay.
- Check for dirty, loose, disconnected or broken wires that will prevent electrical current from reaching the motor. If the wires and connections are in good condition, the starter motor, solenoid or relay have failed, and you need to replace it.
Starter Motor Components
- Main Housing (yoke)
- Overrunning clutch
- Armature
- Field coils
- Brushes
- Solenoid
Checking the Starter Motor
Depending on your particular vehicle model you may need to raise the front of the car or remove the intake manifold or some other component to reach the starter motor. Consult the car repair manual for your particular model, if necessary.
If you need to raise your car, safely support it on jack stands, engage the parking brake and block the wheels to prevent the car from rolling.
- Make sure the starter mounting bolts are tight. Loose mounting bolts will keep the starter drive from properly engaging the flywheel. When this happens, you'll hear a grinding noise as you try to fire up the engine, since the ring gear on the flywheel and the pinion gear on the starter clash, unable to mesh properly.
- If the mounting bolts are tight, remove the starter motor from the vehicle and check the pinion gear — this is the small gear at the front of the starter that engages the flywheel to crank the engine. Check the condition of the pinion gear's teeth. Worn or damaged gear teeth will prevent you from cranking the engine as well.
- Using a standard screwdriver, try to rotate the pinion gear in both directions. The gear should only rotate in one direction. If it moves in both directions or doesn't move at all, replace the starter.
Make sure to watch the following video to get a visual reference of the trouble points you want to pay attention to.
Inspecting the Engine Flywheel
If you removed the starter motor for inspection, this is a good chance to check the flywheel as well. The flywheel is the large, heavy wheel between the engine and transmission. This is the wheel that the starter pinion gear engages to crank the engine.
- Once you've removed the starter motor, set your transmission to Neutral.
- Have an assistant rotate the crankshaft by turning the center bolt on the crankshaft pulley using a ratchet or breaker bar and a socket. You'll find this pulley at the front and bottom of the engine block. This pulley rotates the drive or serpentine belt to run the alternator, steering pump and other components. Depending on your vehicle model, you may need to remove a wheel to gain access to the pulley center bolt.
- Watch the flywheel as it rotates and make sure the teeth are in good condition. Missing or damaged teeth will prevent the starter motor from cranking the engine. Replace the flywheel, if necessary.
Testing the Starter Motor for Proper Operation
If you suspect the starter motor, take it to an auto parts store for testing. Many auto parts outlets will test your starter for free. An aged starter motor may have worn out brushes, armature, shaft, or burned field winding that may cause unusual noises, excessive current draw, slow cranking or no cranking at all.
A quick inspection at an auto parts store will reveal the drive mechanism and motor general condition, whether the starter draws enough current to operate, and the general state of the internal components.
If the previous checks did not turn out anything wrong with the starting system, you still have other simple troubleshooting strategies to further test the starter motor. Check the tips outlined in the article "Bad Starter Symptoms: Why Won't My Car Start?"
When you face car starter problems, remember that lack of proper battery maintenance, faulty electrical connections and components will prevent your starting system from working properly. Whatever the source of the problem, these troubleshooting tips will help you when your car won't start. They'll provide you with a relatively quick way to solve your starter problems.

Questions & Answers
My car is having trouble starting when I turn the key, and then after about an hour, it starts back up again. What’s going on?
You need to make sure you have good spark and fuel pressure. Another issue is poor compression, but this usually happens on high mileage engines. Match the symptoms to the descriptions on the headings. Also, follow the procedures described in the post. This could give you a clue about the problem.
Helpful 58What happens if the wires that connect to the starter from the engine touch?
Those wires come from the power side of the battery. You can produced a bad electric shortcut if those wires touch the engine block itself, for example.
Helpful 44I have a 2017 Nissan Sentra. The first start in the morning is fine. But, if I drive it for more than 30 minutes and kill it, it doesn’t want to restart. It just continues to turn over and over. I can play with the gear shifter and finally get it to start. When it does this, I can smell something that smells like plastic burning. If the engine is cold, it starts fine. It seems to be getting worse. The dealership suggested replacing the wiring harness and ECM at $4000. What is your advice?
You may want to try this first. A circuit with a lot of unwanted resistance is preventing the engine from starting, and probably it’s the starting system. After driving for a few minutes something in the circuit gets too hot-- possibly a wire or connection-- because current can’t flow properly and it’s starting to burn the insulation or a connector. These other two posts may help you locate the fault.
Helpful 4Does the key have to be in the ignition switch when tapping the starter on a 2007 Honda Accord?
Lightly tap the starter as a helper tries to fire up the engine.
I've installed a new starter, but every time I start the truck, I have to push the starter back up and tighten it. I've used pressure washers, loctite, etc., to keep it from loosening but still does it. Why would that be?
Make sure you have the correct starter bolts. Contact your dealer and see if they can tell you the correct size for your application. You can test the bolts outside with the starter removed. If the bolts have any play when put through the starter holes, they are not the correct ones.
Usually, this may not apply all the time, if your starter doesn't have gear reduction, use shims and support bracket as needed. If you don't have the shims but need to install them, you can find starter shim kits in case you need them. You can find videos only about starting shimming as well. Hope this helps.

A new and quality battery should stand its charge for at least a month, unless you’ve fitted your car with high power consumption gadgets. As the battery ages, you’ll see its rate of charge dropping, usually, to two weeks. Of course, you need to take into account your local climate (too hot?) and driving habits. It’s possible your car has a parasitic drain. This other post may help you locate it:

What would cause a starter to sometimes work? When I turn my key to on position, all indicator lights come on and I can hear fuel pump working. When I continue and turn to start position everything goes off until I release from start position. Eventually it will start, sometimes after many attempts, sometimes after one or two, and sometimes it starts right up the first time. Usually after sitting overnight or long periods of time, it starts right up, and when I try starting it within 30 minutes after driving it and shutting it off it seems to work fine, usually but not always.

Hi I had a problem last year, my ford escape was stuck in reverse, turned out I needed a new gear cable, replaced that , now every other start makes a loud wrenching noise. Took it to a different garage, mechanic says take it back to people who replaced gear cable because it's misaligned, so I did that and they found that the starter motor is worn out because of the starting problems but said it's not because of it being in between gears(misaligned gears) confused please help

Hi Geraldine,
If you have access to an multimeter, check that you have enough battery power: 12.4 to 12.6 Voltage is what your looking for. Otherwise charge the battery and try again. Even if you get this voltage, you may want to take the battery to an auto parts stores to have the battery checked. If the battery checks OK.
If the engine cranks and turns, check that you have spark and fuel coming in.
If the starter motor doesn't sound like it used to, probably you have a faulty starter.
Gook luck

Hi CO,
Make sure your battery is actually charged:
* turn the high beams for about 30 seconds, then turn them off
* wait 2 minutes and measure base voltage again
if it is below 12.4V, you need to charge it.
Also, check all the connections in the starting system, from battery to starter motor. Look for corrosion, loose connections, or damaged.
There may be problems with the solenoid, too.
Good luck

Hi Marco,
Make sure the battery is actually charged. A base voltage reading from your battery above 12V doesn't necessarily means your battery is good. Have it checked at an auto parts store, make sure it is properly charged and still good. They will charge and check the battery for free.
If you got a good battery, check the starter solenoid and the connections to it - should be clean and tight. It seems voltage is not reaching the solenoid if you're not hearing anything.
Good luck

Hi jalal
It is normal for the pinion gear to kick in. This is to rotate the flywheel to crank the engine. If you just hear a click when trying to start the engine, make sure your battery is fully charged and all the connections are good. Then check the starter motor. An auto parts store might bench test it for you.
Good luck

Hi MS,
The pinion gear kicks out during cranking. If you have the right starter for your engine model, it'll be position correctly to mesh with the flywheel.
Good luck
Hi where should the pinion gear on the top of the starter be positioned? It seems like its not out far enough.
For several weeks, my car just wouldn't start on the first try and you'd hear a click. 3 or 4 attempts later the car would finally start. Eventually, every component of the starting system was replaced, including the up sized ground cable, starter motor, alternator, and still the same problem. Finally, a mechanic who was highly rated with electrical systems found the answer. The lug terminal attached to the hot lug on the starter was oversized for the lug plus the crimp on the terminal was not a good crimp, the mechanic showed me the ratcheting crimper he used for the new connection. After 25+ starts I know that the problem has been fixed. FINALLY. This was on a 94 Olds Cutlass Ciera. Happy Motoring all.

Hi Sippy,
Make sure the transmission in in Park,
Try putting a little pressure on the steering wheel (if locked) while trying to turn the key to see if it gets unstuck,
May be the key is too worn, wiggle the key slightly and see if this makes it turn, if so, you may need a new key,
Or maybe the tumbler/cylinder or related mechanism is broken and needs to be replaced.
Hope this helps
Good luck
Key would not turn. Solution?
