thanks for the help. but i was wondering if you could enlarge the picture so i can read it or tell me what the labels are. also, a quick question. is the fuel pump supposed to turn on when the vehicle is in the on position, or when cranking? thank you for the help. i really appreciate it.

Sure, there are 2 wires at the fuel pump itself. A ground wire, black, and a power wire, red, running to the relay. At the fuel pump relay there are 4 wires, a ground (black), a black/blue (turns to red near fuel pump for power), a pink/white that runs to the PCM and a black/yellow that goes to the fuse (#2 , 15 amp).

As for the fuel pump, it should prime up when the key is turned to ON but will only stay on for around 4 seconds then kick back off. This is just the priming up for it, it knows it doesn't need to stay on with the key ON engine not running.

Hmm, is definitely a wire issue somewhere then. You will need to take a test light and poke around the wiring I showed you. Make sure the pins that are labeled ground are actually groundingand not getting power somehow.
