As an expert in automotive electrical systems, I can provide an in-depth analysis of what causes an ignition coil to fail. The ignition coil is a crucial component in a vehicle's ignition system, responsible for converting the low voltage from the battery into the high voltage necessary to create a spark at the spark plugs. This spark is what ignites the fuel-air mixture in the engine's cylinders, allowing the engine to operate. When an ignition coil fails, it can lead to a range of issues, from misfires to complete engine failure.
Common Causes of Ignition Coil Failure:
1. Worn or Damaged Ignition Cable: As mentioned, one of the leading causes of premature ignition coil failure is due to a worn or bad spark plug ignition cable. Ignition cables, also known as spark plug wires, are designed to carry the high voltage from the ignition coil to the spark plugs without leaking energy. Over time, these cables can wear out, crack, or become damaged, leading to increased resistance. This resistance can cause the ignition coil to work harder, generating more voltage than necessary, which can lead to overheating and eventual failure.
2. Overheating: The ignition coil operates under high temperatures, especially during prolonged periods of engine operation. If the coil is not properly cooled, it can overheat. Overheating can cause the internal components of the coil to break down, leading to a failure in its ability to produce the necessary high voltage.
3. Voltage Spikes: Voltage spikes or electrical surges in the vehicle's electrical system can also damage the ignition coil. These spikes can occur due to various reasons such as a faulty alternator, a malfunctioning sensor, or even a lightning strike. The sudden influx of voltage can exceed the coil's designed limits, causing it to fail.
4. Magnetic Interference: Ignition coils are sensitive to magnetic fields. If the coil is exposed to strong magnetic fields, it can cause interference that affects its performance. This can lead to a reduction in the efficiency of the coil and, over time, to its failure.
5. Poor Quality Components: The quality of the components used in the ignition coil can also affect its lifespan. Low-quality coils may not be able to handle the demands of the engine and can fail prematurely.
6. Age and Wear: Like any other component in a vehicle, the ignition coil has a finite lifespan. Over time, the internal components can degrade, leading to a reduction in performance and eventual failure.
7.
Faulty Ignition Control Module: The ignition control module, or ignition module, is responsible for controlling the ignition coil's operation. If this module fails or malfunctions, it can send incorrect signals to the coil, causing it to operate outside of its designed parameters and potentially leading to failure.
8.
Incorrect Installation or Maintenance: Improper installation of the ignition coil or inadequate maintenance can also contribute to its failure. For example, if the coil is not securely fastened, it can vibrate excessively, leading to premature wear. Similarly, neglecting regular inspections and replacements can lead to a coil that is pushed beyond its operational limits.
In conclusion, the failure of an ignition coil can be attributed to a variety of factors, including worn ignition cables, overheating, voltage spikes, magnetic interference, poor quality components, age and wear, faulty ignition control modules, and incorrect installation or maintenance practices. Regular inspection and maintenance of the ignition system, along with the use of quality parts, can help prevent premature failure of the ignition coil.

The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil's secondary winding.Sep 23, 2016
