Testing an ignition coil is a simple procedure that can help you determine if it’s time to replace the unit. To test your coil, start your car and allow it to idle for a few minutes. Then turn the key to the “on” position and hold it there for two seconds. If the engine starts, the coil is good. If the engine does not start, check to see if any wires are loose or damaged near the coil. If so, tighten these up and test again. If all seems okay, replace your ignition coil.
