    Default '04 Navigator

    I replaced a coil and plug in the #2 cylinder. In order to do so I had to disconnect & remove the on board computer. I replace everything, and tried to start the engine, but nothing happened. Please help!!!

    Hi NBrown718,

    We really can't diagnose problems from a remote location, but you should check to make sure the electrical connectors are securely plugged into the PCM. If they are,disconnect them and make sure all of the terminals are in good shape to make sure you didn't bend one of them when reconnecting the connectors. Also, did you disconnect the battery before you removed the PCM?

    Curious as to why you had to remove the PCM in the first place - it looks like it wouldn't interfere with the #2 coil and plug.

    Anyway, I hope you can find an obvious problem and get up and running again.
