What can cause an ignition coil to fail?

Main Causes of Ignition Coil Failure

  • Problems starting the vehicle. Check the high tension leads (HT Leads).
  • Damaged or worn spark plugs. If the spark plugs are worn out, it forces ignition coils to operate at a much higher output.
  • Vibrations.
  • Overheating.
  • Wear and tear.

How many ohms should a ignition coil have?

Most ignition coils should have a primary resistance falling somewhere between 0.4 and 2 ohms; however, refer to your manufacturer’s specifications for the correct reading. If a reading of zero is displayed, that signifies that the ignition coil has shorted internally in the primary windings and needs to be replaced.
