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. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.

How do you ruin an ignition coil?
The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.
Can an ignition coil fail when hot?
The symptoms of a bad ignition coil can be hard starting, lack of power, misfiring, and running too hot. These are all signs that the coil is nearing its lifespan and should be replaced in order to make sure that your car runs as it should. A bad spark plug can also cause your car not to start or misfire.
What are the signs of bad ignition coil?
- Loss of Power. This is one of the first symptoms of ignition coil failure. ... - Check Engine Light On. ... - Poor Fuel Economy. ... - Backfiring. ... - Misfiring Engine. ... - Hard Starts and Stalling. ... - Spluttering and Coughing Sounds. ... - Jerking and Vibrating.

What can damage an ignition coil?
Vibrations can damage ignition coil windings and insulation causing shorts or breaks in the secondary windings. The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing.
What would cause a coil pack to keep going bad?
Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle's fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.
Why do my coil packs keep going bad?
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.
What Makes Coil-On-Plug Modules Go Bad? (Ignition Coil Diagnostics)
How do you stop ignition coils from failing?
Keeping your spark plug in optimum condition can reduce your chances of experiencing an ignition coil failure. As spark plugs wear down, the gap in each spark plug is fired is widened meaning the coil needs to provide a higher voltage in order to bridge the gap.
What causes ignition coils to overheat?
Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.

What causes a coil pack to crack?
If not dead flat the out of plane (say one corner high or low) will crack coil when tightened down. The longterm cracking on these that normally occurs after long periods of time is from temperature.
Can you fix a cracked coil pack?
Basically, you apply a 2 part epoxy over the cracks OR the entire plastic housing. The epoxy is non-conductive and insulates the cracks. My coil was very dirty, so I disassembled and washed it so the epoxy would stick.
