    The 5.0L V8 in the 2001 Explorer has two coils - each one firing four plugs.

    The ignition system / spark is controlled by the PCM.

    There is a PCM relay in the battery junction box - the box with fuses and relays near the battery.

    The crankshaft sensor is also one to have a look at to make sure it is sending the signal.

    The processor will be fine; don't sweat that...very rare there is an issue there.

    Does a PCM relay trip at the same time as a fuel pump relay if the fuel pump is faulty?
