4 cylinder to 5.0 conversion

[saleen243]

Last night I crank my car after a month of swapping parts. Just to give everybody a little back ground, here is what I have done: I bought a 89 coupe 4 cylinder and I gutted the car pretty much. I took a 87 GT parts car and swapped all the necessary parts over to make the coupe a V8. I got a 88 mass air harness and all my wiring matched up. I used the helms books for reference. The reason I did the swap was to keep busy from modifying my saleen to the point of no return. Now back to the future:

The car crank and ran fine for about 15 - 20 minutes!!! Then it just stopped running. I turned the key forward but the fuel pump did not come on. The car did crank over but no fuel pump noise etc. I checked the relay under the left seat and it was kind of warm, swapped it out and turned the key froward still no fuel pump. I think the pump died, it was the original 4 cylinder pump and my plans where to run it till it died., then replace it with a 190 pump for future upgrades. I also plan to get a fuel pressure regulator and fuel pressure gauge for the fuel rail. What do you guys think??? Did the pump die or is there something else I should check, when I bought the car somebody has spliced a black wire into the the harness that plugs into the fuel tank and grounded it to the rear bumper. I do not know if this was done because of past problems with the 4 cylinder fuel system. I replaced that harness with one from the 87GT parts car. Where is the ground for the fuel pump located?? I know there is a chasis ground some where. I have another fuel tank standing by to be setup for the new pump etc. Any suggestions would be appreciated???????? Thanks!!!!!!!! Sorry so long but I wanted to present the full picture......
