The ignition system is a vital component of your vehicle’s engine. It is responsible for creating the spark that ignites the air/fuel mixture in the cylinders, which in turn creates the power that propels your car. The spark plugs are the final component in the ignition system, and they are responsible for delivering the spark to the cylinders. However, if the spark plug wires are faulty, it can prevent the spark plugs from receiving the necessary voltage, which can lead to a misfire.
There are a few different ways to test spark plug wires. The most common method is to use a spark plug tester. This is a simple tool that can be purchased at any auto parts store. To use a spark plug tester, simply connect the tester to the spark plug wire and then start the engine. If the spark plug wire is working properly, you will see a spark at the tester. Another way to test spark plug wires is to use an Ohmmeter. This is a more advanced tool than a spark plug tester, but it can provide more detailed information about the condition of the spark plug wires.
If you are experiencing misfires or other ignition problems, it is important to test your spark plug wires to rule out any potential issues. Testing spark plug wires is a simple and inexpensive task that can help you keep your vehicle running smoothly.
How To Test Spark Plug Wires
Spark plug wires are an essential part of your car’s ignition system. They carry the high-voltage spark from the ignition coil to the spark plugs, which then ignite the air-fuel mixture in the cylinders. If your spark plug wires are damaged or faulty, it can cause a variety of problems, including misfires, decreased engine performance, and even a complete engine failure.
Testing your spark plug wires is a simple and inexpensive way to check for problems and ensure that your car is running at its best. Here are the steps on how to do it:
- Gather your materials. You will need a spark plug wire tester, a multimeter, and a set of pliers.
- Disconnect the negative battery terminal. This will prevent you from getting shocked while you are working on the spark plug wires.
- Remove the spark plug wires from the spark plugs. Use the pliers to gently pull the wires off of the spark plugs. Be careful not to damage the wires.
- Inspect the spark plug wires. Look for any signs of damage, such as cracks, cuts, or abrasions. If you find any damage, replace the spark plug wire.
- Test the spark plug wires with the spark plug wire tester. The spark plug wire tester will send a high-voltage spark through the wire. If the wire is good, the spark will be bright and blue. If the wire is bad, the spark will be weak or nonexistent.
- Test the spark plug wires with the multimeter. The multimeter will measure the resistance of the spark plug wires. The resistance should be between 5,000 and 10,000 ohms per foot. If the resistance is too high or too low, replace the spark plug wire.
- Reinstall the spark plug wires. Once you have tested all of the spark plug wires, reinstall them on the spark plugs. Be sure to push them on firmly until they click into place.
- Reconnect the negative battery terminal.

How often should I test my spark plug wires?
You should test your spark plug wires every 30,000 to 60,000 miles. However, if you are experiencing any problems with your car, such as misfires or decreased engine performance, you should test your spark plug wires sooner.
What are the symptoms of bad spark plug wires?
The symptoms of bad spark plug wires can include:
- Misfires
- Decreased engine performance
- Rough idling
- Stalling
- Complete engine failure
How much does it cost to replace spark plug wires?
The cost to replace spark plug wires will vary depending on the make and model of your car, as well as the type of spark plug wires you choose. However, you can expect to pay between $50 and $200 for a set of spark plug wires.
