    check this link for wiring diagrams

    Rob's Creative Calibrations - Wiring Diagrams

    the pump gets it's signal from the PCM, it should turn on for a few seconds when you turn the key to the on position and then stop. once the engine cranks and starts then it turns the circuit on again. have you checked the fuel pump relay and fuse?

    there is also and output on the diagnostic plug for the fuel pump, however i can't remember which pin it is. if you put an LED on this output on the diagnostic plug you can see if the PCM is turning the circuit on.
