2014 Ford F150 cranks but won't start; it seems like an intermittent problem. No codes are being given. The computer was replaced and it happened again. It has been going on for the past week. I'm being advised to replace the MAF and Fuel Module Assembly. I was told it is one or the other. Any thoughts?
This type of intermittent problem usually points to electrical faults. A sensor might not be able to send the correct signal when the fault is there. Check the circuit (wires, connector, harness) for those sensors the computer depends on to manage fuel, and ignition timing. This could be the camshaft and crankshaft position sensor:
throttle position sensor:
or ignition control module.
Check the MAF sensor and circuit, if necessary:
