What's wrong?
 

The car will only fire with the fuel pump diconnected...

I turn the key on and it primes the pump, crank , no fire. Disconnect the pump trigger wire it will fire but die unless I reinstall the trigger wire..

Once I get it fired and hook the pump back up it runs fine...

sound like you have a wire that is not hot in crank and run.

I have checked them, all is good.

From my understanding the pcm only turns the pump back on after it sees a start condition.

The car will only start if I disconnect the fuel pump relay trigger wire.

Maybe the relay is wired wrong?

I figured it out. I had a wire that was only 5 volts when cranking. I remember reading about this and I thought I had jumpered correctly but satistraction's post made me double check it with a volt meter.
