Can a spark plug coil cause a ticking noise and if so how do you fix it?
A coil could cause a light ticking or snapping sound if the insulation is perforated and the high voltage is leaking through the insulation to ground. Perhaps move the suspected coil to another cylinder to see if the noise moves.
Yes, as Bob said. To check this, wait until after dark (no joke) then open the hood and start the engine. You'll see the spark jumping from the coil. HTH. -Jim
Jim is correct, sometimes watching for a spark in the dark will reveal the problem.
