How to Check an Ignition Coil Pack

1. Put the vehicle in park and make sure the emergency brake is pulled up. Open up the hood of the vehicle. Find the coil pack located inside the engine. Disconnect the spark plugs from the spark plug wires. The spark plug wires are joined to the coil pack.
2. Disconnect the coil pack's electrical connector. Utilize the wrench to take off the pack and remove it from the engine.
3. Switch on the meter. Put the ohmmeter to 20000 ohms then touch the meter leads to the coils. This will check the ignition coil pack. Compare the readings to the specs provided in your car's service manual. Determine if the readings you have are in range of the settings in the manual.
