1994 ford150 302 engine missing
I have a 94' 150 302 that is missing. The first thing I did was to look at the engine running at night to see if there was any spark leakage and it looked like the 4th of July under the hood. I have changed coil, spark plugs,plug wires,rotor,and rotor cap. All new parts are from a local part house, not from a Ford Dealer. The miss has not gone away and before I started to work on fuel system I again looked at the engine at night for spark leakage and there are sparks on the coil, wires, and rotor cap. The sparks seem to jump around fron place to place . What am I missing or can all of the new parts be bad?
