The ignition control module is a small electric component that handles a variety of different tasks in the engine. The main responsibility of this module is timing the spark plugs to fire at the correct intervals, ensuring they line up with the rotation of the pistons.

When an ignition module stops working, drivers may encounter all sorts of problems with their vehicle. The most common problem is the car not starting at all, although that issue could be related to a number of different parts. You may also experience intermittent stalling, only to find that you are able to continue driving shortly thereafter. This means the engine is backfiring, and could be damaging your pistons and valves. Thus, it's better to replace an ignition module at the first sign of trouble rather than wait and risk further damage to critical parts.

Since a variety of parts can cause ignition issues and stalling, it's a good idea to check the ignition module first. This is an electrical component, so it can be checked using a digital multimeter. This device can read the number of ohms coming from a certain part, and will essentially tell you whether the part is working or is dead completely. Keep in mind that this test isn't 100 percent accurate - the ignition control module has many small electrical components, and part of the module may be functioning and giving off ohms while the other isn't.

A multimeter is a handy device to have for those who work on their car, as it is useful with just about all the electric components of a vehicle. They can be found at any auto parts store, but if you'd rather just find out about the ignition module, many stores will perform this test for you free of charge.

If it turns out your ignition control module isn't working, it's fortunately an easy repair. First, know that ignition modules are not a "one size fits all" type of part. They vary in size and design based on the make and model of the vehicle. You'll probably be able to find the right one simply by talking to the experts at the auto parts store, but it never hurts to look up the exact part in your owner's manual just in case.

Once you have the replacement part, changing it out is a snap. Whenever you're working with electric parts, the best first step is to disconnect the battery. Locate the ignition module in your owner's manual, then grab a Phillips head screwdriver.

The most important thing when performing this repair is taking care not to damage other wiring. There are likely other components located in this part of the car, so take care to gently move them out of the way and go slowly to prevent damage. Disconnect the old ignition module from any wires that it is attached to and remove it from its plug. Then, use the screwdriver to remove the mount screws that are holding the module in place.

Now take your new module and install it exactly the way the old one was. Make sure it's mounted tightly using the screwdriver, then firmly plug in all wires and connections. You can use the multimeter or a test light to ensure the part is working. Finally, reconnect the battery, turn on your car and the problem should be fixed.
