Most diagnostic devices then ask for some information about the vehicle. Can my 13 year old choose to live with me? Remove the coil and leave it to dry on some tissue paper. . Defective sensors. Ignition coil failure may cause the engine to struggle upon starting or prevent it from starting at all. The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. Another ignition coil failure cause is when a spark plug has an improper plug gap. If you notice that all of the cylinders are improperly timed, it could reveal trouble with the flywheel key. This excessive voltage creates a high amount of heat which consequently melts the coil's wire insulation. When buying a new ignition coil, ensure that youre buying the one for your car. Note: This method only works on vehicles with coil-on-plug (COP) type ignition coils, and will not work on coil packs. Ignition is all about precise timing, efficiency, and consistency.It's arguably the most important system when it comes to internal combustion engines. .
