Well i got a 94 bronk as my mud truck. Ran awesome for a few months, mostly jumping the piss outta it. Well I was doing a huge jump and then I landed and it stalled out. No fuel pump. So I checked for power at the intertia switch none, ran a power wire too the swith to see if it would work. Yess it runs, but still doesnt start. Started to ck fuses and relays. Good, checked for power and ground to the ECC relay and Fuel pump relay. I have power but was losing it goin to the ecu, found corroded wire at ecu, got power at ecu now, still no start, fuel pump still not running, LB/O is the ecu ground sig, for the fuel pump relay, wire good to the ecu, if I add ground then the pump runs, still no start, have to ck for injector pulse and spark, but thats hard alone. Anyone think bad PCM also?
I did that 1 time in my bog truck, the battery had jumped up and shorted out on the hood, causeing the ground wire over by the heater box to fry in two. replaced that wire, and all problems resolved
