How do I know if my coil is firing?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.
Is it my spark plug or ignition coil?
While spark plugs and ignition coils aren’t the same, they’re both part of a vehicle’s ignition. Or rather, part of a gasoline-powered vehicle’s ignition system. Diesel engines don’t have spark plugs because diesel ignites via compression, not a spark.
