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.

Backfiring

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.
