So after spending a couple days hunting I figured I'd go ahead and pick the brains of others. 1996 S14, RB25, wiring specialties harness, fuel pump inop. The chassis had a running VH in it a month ago with zero issues. I've been searching the internet for days and thus far I'm stumped and it doesn't seem like anyone else has had a similar issue.
Pump won't prime/run. I've verified good grounds at F14, F15, T16, M5, and M57. 12V going to the relay, 12V going to the pump assy. I've swapped ECU's 3 times, swapped pumps, tested pumps, swapped relays just for giggles, and still nothing. Pump is a drop in replacement Aeromotive 340 and I've also tried the Walbro 255. Factory wiring as far as the chassis is concerned. I know the pump is ground triggered by the ECU, but I don't know how I still can't have fuel after trying all these things. I've attempted to contact wiring specialties and that has not been fruitful. Can anyone think of anything that I might be missing?
