Q: Plugs not sparking.

asked by on

My spark plugs are not working. What could cause this?

Hi there! Spark plugs usually stop working due to old age. Spark plugs conduct electricity through the electrode of the spark plugs to ignite the fuel. An electrode will become shorter after each ignition just as a candle wick would. If the wick becomes too short it won’t be able to ignite the fuel, crippling the spark plugs from being able to work. Depending on how much of the electrode is left, you may be able to adjust the gap of the spark plug itself. A certified technician would be able to replace the plugs, as well as adjust the spark plug gap to possibly extend the lifetime of your current spark plugs.
