Are you getting power to the fuel pump relay? Good eec ground? Does the pump run when jumpered?

I found a diagram that tells me that im missing one thing that the coolcats info did not tell me. I need to add a wire from pin 19 to the fuel pump relay. That must be why its not starting. Oh and could some one let coolcats now that so no one els runs in to it too thanks. I have the diagram and the page i found it on if any one wants to see it too. Thanks for the help haystack

You don't need to add a wire from pin 19. I didn't and it runs fine. I'd check for other issues.

Yeah, that is just an optional fuel oump status monitoring wire or something like that. It will throw a code, ut not effect anything or turn on your check engine light. You have another issues. Try jumpering the fuel pump to run it, and check for power at your relay.

Check pins 20 40 and 60 for ground with the computer disconnected. The if the ground is bad to the computer, or the computer relay itself, then the fuel pump relay will not get tripped. So check all your ground pins and make sure you have good condituity, then check for power too and from the computer relay.

I think it is going to be something stupid like a plug got disconnected, fried fuseable link by the battery tray, or maybe a grounding issue. Maybe eec relay.

Check the black grounding wire that goes from the battery to the fennderwell, then goes to a black plug to the injector harness. Make sure you have good ground between that wire and the computer.

The jumper for the pump just bypasses the relay. You basically need to find out why the relay isn't being tripped.

Well, go over the things you changed. There was a no start thread I started where tom renzo pointed out pins that could be burnt up on the computer. Have you seen that computer work in another car?
