    The engine starts fine but dies almost immediately. If I give it gas to keep the RPMs around 3000, it still dies after a few seconds. The pressure switch on the fuel rail will squirt fuel if I depress it. Thoughts?

    What year is your car? Because some keys have a chip in them and if you get a copy of a key and don't have the chip in it, the car will start fine and then die. Yea I went and made a copy and tried starting the car and then it died.

    MAF sensor? fuel pump? fuel pressure regulator? my car did the same thing and it was my MAF sensor. if you unplug it and the car starts, its a bad MAF. as far as the other things go, i havent had them go bad i just know they could possibly cause that

    It's a '97 but not a new key.
    CTKGP09 - will the car run with the MAF unplugged? Or should it not start at all with the MAF unplugged?
    It acts as if it is starved for fuel after a few seconds so it could be the fuel pressure regulator or my father in law thinks it might be the throttle position sensor.

    yes if the car starts with it unplugged then the MAF is bad, if you unplug it and the car still doent start then its something else. the throttle position sensor is a good guess too...forgot that one

    BigmeadersGTP - Bingo! the fuel pump resistor appears to be the issue. When it is bypassed it runs great. I'll pick one up tomorrow and hope to be on the road. Thanks!

    Fuel pump resistor relocation kit did the trick. Drove 600 miles this weekend with no issues. Thanks everyone for the ideas.
