I've gotta '92 5.0L f-150 and it's doing something VERY strange... When I move the distributor like you would when you set the timing/advance, the engine is off, and the key on, it will at a certain spot trigger the fuel pump to prime... Which to me is very abnormal, I wiggled the wires and checked for wiring faults in the harnesses, to see if I could get it to do it that way, no luck, only happens when I rotate the distributor. Any help would be great, Thanks
