So it it might not be the fuel pump since the relays are clicking and if I power the pump from test wire it runs. so maybe computer?

I dont have a bonnie so I'm guessing, follow the wires from injecters, mine lead to a plug for all of them.

If you can get to each injecters plug you can do it that way also, just do 1 at a time! If there is a short it can shut the computer down, fuel pump relay down also.

The injector plugs are very easily reached they are right out in the open along the front of the fuel rail and along the back if you need a picture let me know i will go take one for you

Okay let me ,make sure I under stand should I turn the key to on position the pull each injector one at a time to see if the relay stops clicking. and I got to hope it clicks because sometimes now it will not click and car will start then die a friend I had by the relays when I started the car said he heard the relay click right before it died then it started clicking for a bit again

I forgot to say when I had it started it I reved it up but when ever it got to around 4000 rpm it would I guess I would say stutter (maybe pulsate) I don't know how to describe it

Sounds like that relay is bad. That'* the power supply to the fuel pump. If it'* clicking the the power is turning on and off. I would replace the relay.

At about 4000 rpm your hitting the rev limiter. Hit that and the RPM drops, then revs back up until it hits the rev limiter again.

I have traded the relays with others that were exactly the same and the relay would click too. I was reading earlier in a thread a guy with the same car year motor everything, was having the exact same problems I was before it started not staying running. he explained better in his thread the symptoms is I can find the thread I'll give a link to it
