    I've had fun with this car the last few months. 3.1/ Replaced a burnt harness to the crank sensor then the fuel pump goes out. I lowered the tank and made an access in the trunk and also replaced the filter. I have been driving it for over a week now. Yesterday I pulled from a parking spot and it cut off.
    The pump runs,it has spark but will not start. I have not checked the fuel pressure yet but the pump turns on and primes for about 3 seconds then turns off. Could the pressure be low and not let the injectors open? Tim

    The injectors are opened electronically not by pressure. Have you tried starting it with starting fluid?

    open the bleeder on the fuel line and drain the fuel out of the line then turn the key to on position 2-3 times to put fuel back in the lines check if there is fuel in the lines by the bleeder if so pump is ok
    now try to start car with starter fluid does it start then die?
    if so try cleaning injectors
    if it stays running good

    It starts with starter fluid then shuts down when it burns up.
    The bleeder is the shrader valve where I check the pressure correct?
    When I remove the shrader valve cap I can hear pressure leaking. I'm not sure how well it's sealing with the cap on.

    I'm sure I need to replace the shrader valve from hearing the leak.
