If your car’s engine is starting to misfire or notturn over as easily as it used to, it might be time to check the ignition coil. This small part of the engine can go bad over time and cause all sorts of problems. In this blog post, we will walk you through the steps necessary to check which ignition coil is bad and how to fix it.
How to Check If The Ignition Coil Is Bad
If your car won’t start, the first thing to check is whether or not the ignition coil is bad. This is a small, inexpensive part that can usually be replaced without causing too much trouble. Here’s how to check it:
1. Disconnect the battery cables.
2. Remove the air cleaner assembly.
3. Check that all of the connectors at the coil are firmly connected and in good shape (they should look like they’ve been used a few times before and not just freshly assembled). If any of them are loose, replace the connector.
4. With all of the connectors attached, reattach the air cleaner assembly and connect the battery cables. Start your car and see if it starts. If it does, then your coil is probably bad and you’ll need to replace it.
How to Replace An Ignition Coil
The ignition coil is a small, electronic component that helps start your car. When it fails, your car won’t start. There are several ways to check which ignition coil is bad and replace it.
If the car will sometimes start but then dies after a few minutes, the problem could be with the Ignition Coil Pack (ICP). The ICP contains two coils: the primary and secondary. The primary coil generates electricity when you turn the key in the on position. The secondary coil supplies voltage to the starter motor. If one of these coils is bad, it can cause trouble starting your car. To test if one of these coils is bad, you can remove it and test it with an ohmmeter (or multimeter). If there’s no resistance when you touch the leads to each coil with an ohmmeter (or multimeter), then that indicates that the coil is bad and should be replaced.
If your car starts but then stalls after a few seconds or minutes, the problem could be with either of the spark plugs or wires connected to them. To test if one of these spark plugs or wires is bad, you can remove it and test it with an ohmmeter (or multimeter). If there’s no resistance when you touch the leads to each plug or wire with an ohmmeter (or multimeter), then that indicates that that particular spark plug or wire might be bad and should be replaced.

How to Test A Spark Plug
Spark plugs are one of the most important parts of your car’s ignition system. If they don’t work correctly, your car won’t start. Testing a spark plug is easy and can help you diagnose any problems with your ignition system.
To test a spark plug, you’ll need:
1) A spark plug tester
2) A ground wire
3) A screwdriver
4) A socket wrench (or ratchet)
5) An air hose
6) A bucket or container
7) WD-40 or equivalent lubricant
8) Your car keys
Step One: Remove the fuel cap and unscrew the spark plug cover. Carefully pull out the spark plug. Note the position of the electrode (the metal part that makes contact with the IGN). If it’s worn or damaged, replace it now. Step Two: Strip 1/2 inch of insulation off each end of the ground wire and attach one end to the screwdriver blade, making sure it points away from you. Touch the other end of the ground wire to one end of the electrode. Try to start your engine and see if there is enough voltage to light up a light bulb. If there isn’t enough voltage, check Step Four below. If there is enough voltage, congrats! You’ve found a good ground wire connection.Step Three: Screw in
