Truck lost power while driving for about 3 minutes. Wouldn't accelerate quickly at all problem went away but now came back. No power whatsoever, cannot even take off from Drive. Noticed fuel pump is constantly running KOEO. Fuel pump relay clicks every now and then. Check engine light is on but im only getting a code 111. Every time the fuel pump relay clicks the check engine light flickers KOEO. Seems like it has a miss at idle. Also i noticed overdrive does not work when its messing up...Before everything started I changed spark plug wires and put a tank of gas in it. This only happens occasionally while driving and once I cut it off and restart it's fine for a while. Im thinking maybe the PCM/ECU is grounding out or is fried. Any help would be greatly appreciated. 1994 F150 5.0 E40D Overdrive.
