HELP car starts for a second and shuts down

[Sponhower]

This is a new one for me! The car starts and then immediately dies. I put a fuel pressure gauge on and after the pump stopped running the pressure went to zero. So I guessed that it was either the pump or fuel pressure regulator. Regulator was easiest and cheapest to fix so strike one. Then the pump, strike two. Then I changed the plugs and wires and you guessed it I'm out of ideas. If anyone could help I would greatly appreciate it. Thanks

check the cam sensor and crank sensor and maf. Do you have a scanmaster, that would help alot.

Do you know if it has an aftermarket chip? Some chips, like the Trasher, had an anti-theft mode. It would allow the car to start and run on the fuel in the rails for a second or two and then die. That is, unless you knew the secret way around the anti-theft mode. :idea5:

It does have a thrasher chip could it be that easy?? What is the way around it.

I'm having the same problem, though I've performed fewer troubleshooting steps at this point. The "dealer" didn't have the original keys and had to have a set made, maybe I have a theft issue as well?

If you have another chip you can swap in, stock or otherwise, this might be something easy to try.

Nope, know where I can get one, maybe used?
