If your engine is giving you trouble, one of the first things you should do is check the ignition coil. This component can easily go undetected and cause all sorts of issues down the line. In this blog post, we’ll walk you through the simple steps necessary to checking an ignition coil. ###
What is an Ignition Coil?
An ignition coil is a coil of wire used in an engine to produce sparks that ignite the fuel. The coils are usually in pairs and are situated around the crankshaft. When the spark plugs ignite the fuel, it travels up the coil to the spark plug.
How to Check an Ignition Coil
If you’ve ever noticed an unusual “spark” followed by a dead engine, it might be time to check your ignition coil. The ignition coil is responsible for igniting the air/fuel mixture in the engine, and if it’s issues, it can cause poor performance and even a blown engine. Here’s how to check an ignition coil: Remove the spark plugs from the cylinders. Turn the key to the “on” position but do not crank the engine. Now connect an ohmmeter across each plug wire (or use a voltmeter) and read the voltage. If there is no voltage at all, then your ignition coil is bad and needs to be replaced.

What to do if the Ignition Coil is Not Working
If you’re having trouble starting your car, there are a few things you can do to check the ignition coil. First, try turning the key all the way to the “off” position and waiting a few minutes. If it still doesn’t start, you can try resetting the car’s computer by disconnecting both battery cables for 10 seconds, then reconnecting them. Finally, if none of these tips work, it may be time to take your car into a repair shop.
