Ok , I'm new to this site, the members here seems to be a wealth of knowledge and hopefully I can find my issue. 1992 mustang 5.0 hb, 5spd, bone stock. Here's a run down of what's going on and what I've done. Car ran fine on a day it was pouring out.... shut it off, went to restart it 5 minutes later and it wouldn't start. Fuel pump wasn't on I assumed blown pump. I was late for work so I just parked it and took my truck. 2 weeks later I have a few hours to tinker... tested the pump with no power, tested the fp relay power source, 12 volts at 2 wires, nothing going to pump. Replaced both FP and EEC relays. EEC relay clicking, still nothing from FP relay. Tested FP jumper at OBD1 port. FP turned on. Tried to run codes with jumper wire and KOEO test.... CEL was on dim.... No flashes. After 6-7 tries got coded for 40,60, and tps. Nothing else. CEL stays on dim except when cranking . I pulled the ECU, no obvious damage or corrosion. Plugged in my breakout box. Tested pin 1 had 12 v. Decided to do the grounds next. 40,60 both ground out fine.... pin 20 has no continuity to ground. Is it supposed to? I checked from pin 20 on the harness to the batter neg and it had continuity. 're- connected the ECU to the breakout box, checked continuity from pin 40 to 60, good, 20 to 40 no good, 20 to 60 no good. Jumped 20 to 60..... CEO came on bright, key on, fp kicked on. Car started.... 1week later went to tinker some more, another down pour.... found right kick panel wet..... pulled the the ECU..... it was wet inside.... so obviously I have a leak..... but with pin 20 not having ground should I assume bad ecu?
