    Default 1997 Suburban won't start

    My 1997 Suburban will not start, I have:
    1: Changed fuel filter
    2: Changed fuel pump twice now 60PSI
    3: Changed plugs and wires
    4: Changed rotor and cap
    5: Jumped senser so fuel pump is running (fuel pump does run but jumped it anyways)
    The suburban will start if I pour gas in the throttle body and will continue to run as long as I feed it gas. Once I stop pouring gas in it dies.

    If it runs when you pour gas into the throttle body, that suggests a fuel problem. Have you checked to see if the fuel injectors are firing?

    Thanks for your response. Would not know how to check the injectors

    If you try to start it, then pull a plug (or plugs) are they all wet with fuel?
    If you can get a "noid light" on the injector circuits, you can see if the PCM is commanding them to open.
