    Q:
    How to inspect and replace Ignition Coil and spark plug wires on Ford Expedition? Posted by Customer
    A:
    First of all, apply the silicone dielectric compound inside each boot after detaching a spark plug wire. Replace and check for spark plug wires while you're installing new spark plugs. First off, watch for damage to the wires as the engine runs, starting with cylinder number one. The other wires should be inspected and made sure they are well fastened. Also, clean them up and see if there are any cracks on the coil packs or carbon tracking problems.

    Q:
    How do you check the electronic integrated (El) ignition system for proper operation for the 1998 Lincoln Navigator? Posted by Customer
    A:
    To check the electronic integrated (El) ignition system, start by disconnecting the electrical connector(s) from the coil with the ignition off. Then, use an ohmmeter to measure the resistance between the coil positive (+) terminal and each negative (-) terminal. The resistance should be the same for each check and should match the specifications listed. Next, connect the ohmmeter between the secondary terminals of each coil pack, which are paired according to the companion cylinders. Again, the resistance should match the specifications. If the resistance is not correct, the coil should be replaced.

    Q:
    How do you check the electronic integrated (El) ignition system with the coil over plug (COP) system for the 2000 Ford Expedition? Posted by Customer
    A:
    To check the electronic integrated (El) ignition system with the coil over plug (COP) system, start by disconnecting the electrical connector(s) from each coil assembly with the ignition off. Use an ohmmeter to measure the resistance between the coil primary terminal (+) and the negative terminal (-). The resistance should match the specifications listed. Next, remove the COP assembly from the cylinder head and connect the ohmmeter between the secondary terminals, which fit over the spark plug. Again, the resistance should match the specifications. If the resistance is not correct, the coil should be replaced.
