I have a 1992 Ford F150 the motor runs but the number 2 and 5 cylinders do not fire correctly it has brand new rotor, cap, wires, spark plugs the history of the truck the problem came about from a ground for the fuel pumps and whatever else it was for disconnected and i think it shorted something out I'm not real sure so if you could help me that would be awsome
