Use a spark tester to check the ignition coil. This high resistance causes a very high amount of voltage to be generated from your ignition coil's secondary winding. Issues like spark plug gapping, leaking valve covers or moisture. However, most of the time this issue is due to the ignition system.
When they go out, you can have a misfire, coil packs not functioning properly, or a no-run / no-start situation.

Pinpointing an issue It’s important to remember, that there are a multitude of other sensors and situations on a vehicle not related to the above scenarios that can cause a misfire. What would cause a coil pack to go bad? A faulty coil pack can be caused by a number of things – environmental factors, heat, engine oil seeping through the spark plug holes and onto the coils themselves,. First the spark plug could be bad causing the coil to go and secondly the. .
If the reading falls outside the normal resistance range, you’ll need to replace the ignition coil. Cars with coil packs usually have them mounted near a valve cover. Even with pre-made coils and tank bases I would suggest using an Ohm reader, just to check.
This excessive voltage creates a high amount of heat which consequently melts the coil's wire insulation.
