Cranks runs a few seconds quits. I have replaced everything; alternator, crankshaft sensor. I've checked the ignition of check this computer board. when I turn the key on there are no warning lights coming on on the dash. there's fuel getting to the engine compartment. I'll check that rotor button distributor cap. I don't know what else to do. only thing I have not checked is the key or the key fob.

Hi.

Is the fuel pressure within the manufacturer's spec? Also, is the anti theft light on?

Do me a favor. Check to see what the fuel pressure is so we know it's good. If it's too low, the engine won't run.

Here is a link that explains how it's done. You will need a fuel pressure gauge, but most parts stores will lend one to you.

Here are the manufacturer's specifications for pressure:

Key On Engine Off .................... 60-66 psi

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
