A worn-out ignition coil can cause the engine to misfire or not run at all. A coil fails because it has become worn and is no longer able to transmit the high voltage and charge to the spark plug. Over time, the plastic housing becomes brittle and the metal core gets fatigued from high temperatures. The result is a misfire, and the spark will not reach the spark plug and will need to be replaced. Unfortunately, most manufacturers don't publish a service table, which makes it difficult to tell whether the ignition system needs replacement or if the coil is a common part that needs to be changed.

To determine whether your vehicle has a coil problem, check the battery voltage and the engine's fuel level. Using a multi-meter will show you the proper voltage level for your car. If you find any of these problems, your vehicle might need a repair. If your car runs poorly, your engine will not fire properly. A faulty ignition coil can cause the check engine light to illuminate. If you suspect that the ignition is not working, you can scan your car's diagnostic computer and find out exactly what the problem is.

Another way to test the ignition coil is with a multi-meter. This device is specially designed for modern coils and distributors, and attaches to the wiring to measure its resistance. The test will indicate whether the charge passes through the wiring. In addition to a multi-meter, you can also use a multi-tester to determine the resistance of the inner and outer coils. If the resistance test fails, the coil needs to be replaced. Sometimes, a bad coil will pass a resistance test, but it might be a bad one. In this case, your car's spark plugs and plug wires can also damage the ignition unit.

A bad ignition coil is usually caused by a number of different problems. The vehicle will not start or run properly. It will be hard to drive without the check engine light. If the check engine light is illuminated, you should replace the ignition coil. You can do it yourself, or hire a mechanic. The best way to diagnose a coil problem is to scan for error codes. You can use a multimeter to check the resistance of the coils.

The electrical system of a diesel engine depends on compression to ignite the air/fuel mixture. The ignition coil is a vital component in a diesel engine. This is why you need to have your car checked if the check engine light is illuminated. You can also try a bleeder for the ignition coil. There are a few signs that you should have a good problem with the ignition coil. The problem can be a simple mechanical failure, or it can be a symptom of a more complicated issue.
