The car ignition ignitor or ignitor control module is usually located inside the distributor, though it may be a separate component. It is responsible for the basic process of starting your car, and in some vehicles, advances or slows the engine’s timing. It works by amplifying the signal from the ignition reluctor and sending that signal to the engine control module. This sends battery power to the primary ignition coil and causes your spark plugs to fire. If the ignition ignitor fails, your vehicle will run rough or your engine may not start.

Ignition ignitor replacement is not a part of routine maintenance. | A faulty ignition ignitor can cause your car to be difficult to start. | Other problems can mimic a faulty ignition ignitor.

The battery is disconnected and the distributor cap and rotor removed | The defective ignition Igniter is removed | The new ignition ignitor is installed | The distributor rotor and cap are reinstalled | The engine is started and ignition checked

The ignition ignitor is not replaced or checked as part of regular maintenance. If you suspect your ignition ignitor is faulty or the ignition system is not working as designed, have one of our expert mechanics inspect and replace the ignition ignitor.

Other components, such as a weak battery, contaminated fuel, or fouled spark plugs could cause similar problems. If the problem persists, you should get one of our mechanics to diagnose the problem. It could be the ignitor or something else in the starting and fuel systems.
