Lincoln LS Ignition Coil

Signs that Your Lincoln LS Ignition Coil is Failing

Have you ever wondered what makes your car start up? This is primarily the Lincoln LS ignition coil's responsibility. By working with the rest of the ignition system, this component can power up the engine smoothly to start your vehicle. However, when you are having problems starting up the engine or are experiencing other issues, then there must be something wrong with the ignition coil. Take note of these three common symptoms and know how to diagnose them properly.

Starting problems

If your car's engine can't spark, then there will be no fire. This spark is created by your vehicle's ignition system where the coil is. Start by testing the ignition coil. To test this component, you will need a multimeter that can measure impedance. If you don't have access to this device, you may also perform an alternative test using simpler tools.

Also, check the high-tension leads (HT Leads). These things run between the carburetor and spark plugs. Ignition coil failures could result in one or more spark plugs not receiving the appropriate amount of charge. If you have trouble starting your car in the cold, then this is also a positive sign of ignition coil failure. You can run a simple test on the HT leads to check whether there is in fact a spark going from each lead to each spark plug.

Lower fuel economy

A weak spark from a failing ignition coil will produce less voltage. Less voltage means that the spark plugs will not be able to burn the fuel mixture efficiently. This can produce black, unburned fuel that can be seen at the tail pipe, and is also the cause of lower fuel economy.


If you do not notice the earlier symptoms of a faulty ignition coil, your car may begin to experience serious backfires. This happens when unused fuel is emitted through the vehicle's exhaust, thereby creating a small explosion. Backfires can occur either in the car's manifold or in the exhaust pipe. Usually, backfires caused by ignition coil problems happen in the exhaust pipe. If this is not corrected, these backfires can cause serious damage to your exhaust system, which will require expensive repairs that would have been unnecessary.

  • How to Keep your Lincoln LS Ignition Coil in Great Working Order

    It's sometimes hard to wrap one's mind around the fact that classy cars like the Lincoln LS can be rendered useless by something as simple as a faulty ignition coil. Considering that this little part is responsible for kick-starting the process of getting your engine churning, having it broken is not so great a thing. You might as well have spent millions on an over-priced lawn ornament. As in all things, the key is to be prepared-to address the "problem" even before it actually becomes one. Here are a couple of thing you can do so that your ignition coil will less likely reach the point where it causes you trouble.

    Visual inspection

    A visual inspection of the ignition system is always recommended before subjecting the ignition coil to a thorough test. This is because an entry in the error buffer that indicates a problem in the ignition system doesn't always make the coil the culprit. It is also possible that the problem might be system-wide. When inspecting, make sure to check the following:

    • Whether there is any mechanical damage or hairline cracks present;
    • Whether the electrical wiring and the plug are intact and free of corrosion and kinks;
    • Whether sufficient supply of voltage is provided by the battery; and,
    • Whether all valve seals are still intact.

    Testing the ignition coil

    Whether you are experiencing problems with your ignition coil or not, it is important that you regularly test the component. If you don't know where to start, try these tips:

    • Park your car in a safe place before doing the testing.
    • You can locate the coil by following the spark plug wires to the distributor, then the wire that's coming out of the center of the distributor cap. If your car has a distributor-less system, then the spark plug wires will connect to the coil units, each with two plug wires attached to it.
    • You can leave the coil mounted in place if you have easy access to it. Otherwise, remove the component using a wrench or ratchet and socket of the appropriate size.
    • Make sure that the coils' electrical contacts are free of dirt and corrosion, and clean them if necessary.
