fuel pressure bleed down, possible fuel pressure regulator or injectors
Check for codes(possible cam sensor), check fuel pressure bleed down(possible fuel pump).
A bendix.
could be the starter or the solenoid, they arer pron to heating up especially when using headers, peace
Usually when hot? Could be a starter going bad
The fuse box under the hood. It is the #9 relay and when it starts to go bad there is a delay before engine cranks over.
Stuck relay or the starter is wired incorrectly.
If you can crank the engine over by turning the key: First connect a voltmeter and an ammeter. Then disable the ignition. Note the voltage and amp draw of the starter while cranking. If voltage is too low or amperage too high (check service manual for specifications) it is bad. Otherwise, remove those meters and use an oscilloscope to look for any irregularities in the waveform. If any irregularities exist, the starter is bad. Otherwise, it is probably good. If you cannot crank the engine: Check for BatteryV- at the body of the starter, BatteryV+ at the big wire to the starter and (only while turning key to crank) BatteryV+ at the small wire to the starter. If one or more of these is not present, correct this problem before continuing testing of the starter. Now check that the starter makes some sound (at least a click) while turning key to crank If not, starter solenoid (part of starter) is bad. Otherwise, remove starter from engine but leave electrical connections in place. Turn key to crank. If it doesn't crank, starter is bad, otherwise starter cranks and proceed to testing as if you can crank the engine by turning the key as described above.
If the engine cranks & cranks & cranks before it starts even though it's warmed up already.
Would be in the distributer or the ignition module
No, The compression test is done as the starter cranks the engine
you have a bad solineiod in your starter go get a new starter
When you turn the key in your car, the key turns the starter motor, which inturn cranks the flywheel of your motor. Once firing is accomplished the starter is released, as you release the key. If your motor, just cranks and not start, you may have jumped your timing and this will have to be restored by a mechanic, as the timing belt needs changing.
