1. Cracked or damaged distributor cap: Inspect the distributor cap for any cracks or damage that could allow electricity to arc to ground. Replace the cap if necessary.
2. Worn or damaged spark plug wires: Check the spark plug wires for any damage or wear that could cause the electricity to arc to ground. Replace any faulty spark plug wires.
3. Incorrectly seated spark plug wires: Make sure that the spark plug wires are properly seated in the distributor cap and on the spark plugs.
4. Defective ignition coil: The ignition coil provides the high voltage electricity needed to spark the spark plugs. If the ignition coil is defective, it can cause the electricity to arc to ground instead of traveling through the spark plug wires.
5. Bad distributor: The distributor is responsible for distributing the high voltage electricity from the ignition coil to the spark plugs. If the distributor is defective, it can cause the electricity to arc to ground instead of traveling through the spark plug wires.
6. Excessive moisture or dirt: Moisture or dirt on the distributor cap or spark plug wires can cause the electricity to arc to ground. Make sure the engine is dry and free of dirt.
