So I dropped a 91 5.0 302 into my 97 F150. The motor was running mint, but to much fuel was being pumped into the carborater. So I put a fuel regulator on it. Last night I cut a bunch of wires on a harness from the old electronic setup that wasn't being used anymore. Now I have no fuel being pumped into the engine what so ever? Could the wire harness be the problem? It was never hooked up in the first place and it ran perfect.

Help please, I'm stumped...

 

sorry can;t help with your problem but would love to see some pics

 

haha thanks anyways firefighter. I will be sure to put some up tomorrow for you...

 

The 302 was EFI in 1991. Check power at FP and FP relay, does the pump run? dirty filter?

 

soundsl like you cut one of the wires in the fuel pump circuit. Where are you taking power for your coil from?
