I have an intermittent problem with my 5.8L 1991 Bronco that I need some ideas on.
Drive it for a while and it shuts off, no warning, sometimes when idling, sometimes when on the gas.
There is no hesitation or rough idle before it craps, just shuts off like the key was turned.
Will not restart without first turning the key all the way off. Then it starts right up every time as if nothing were wrong.
Once again, it I try to pop it into neutral and restart, it will not restart, just turns over. If I pull over, turn the key off and then start. It comes on just fine.
I have new:
ignition switch, distributor, rotor, cap, TFI module, fixed old electrolytic caps in the computer that were bad, new battery, alternator, IAC, solenoid, EGR valve, Throttle position sensor is good, new relays, fuel pressure is good, new vacuum lines, 5 year old coil but it seems to be outputting good and input signal/connection is solid.
Hot/cold doesn't matter.
Pulled codes and only get 11, systems checks OK.
Done every line, hose wiggle test I can think of looking for intermittent shorts.
I'm about ready to surrender.
Any ideas?
