How do you test a bad coil?

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.

What happens when an ignition coil goes bad on a Mitsubishi?

Can a spark plug be removed from the ignition coil?

Using a regular spark plug will give a false test result that’ll have you chasing the wrong diagnostic path/conclusion and in the process wasting time and money. Do not remove the spark plug wire from the spark plug or the ignition coil while the engine is cranking to test for spark. This method will ruin the ignition coil.
