Well, if your pockets are deep enough, keep throwing parts at it, and you’ll find the answer.

Or, save some money and do a proper diagnostic. Check for spark at the cylinders. If OK, rule out the ignition system. Check for proper fuel pressure. Is this TBI? Remove the air cleaner, and check for fuel flow from the injector. Is it multi-port EFI? Use a fuel pressure gauge at the test port.

If all checks out, then check to see if the distributor is moving. Remove tha distributor cap, and see if the rotor turns when cranking. Then check the base timing. If it is way off, you may have an issue with the timing chain or belt.

What exactly does it do and not do? If it won’t crank over then why would you work on an ignition module, coil pack or crank sensor, that might be a battery solenoid starter cables etc.

OK you turn the key… Does the starter turn the engine? Is there any sound? Does anything happen? Do the lights dim? etc.
