The car starts but turns off after a few seconds. I put in a new fuel pump, fuel filter, fuel regulator, new spark plugs, it sparks just won't stay running... What could the problem be?

welcome to the forum, thanks for the donation. I saw what you replaced, I'd still have to use a gage and check fuel pressure.

I'm not sure of engine litre size? If you have the bypass ignition system, during cranking it is the ignition module that controls spark timing, after it starts the pcm controls spark timing. Are there any trouble codes?

I guess anything is possible, did you check for trouble codes?

You place jumper wire between terminals A & B terminals of datalink connector. Turn key on, no crank, then the check engine lite starts flashing, you count the flashes to get the codes.
