Engine Controls - Basic Testing: Spark

  1. Crank engine. Check for a strong Blue spark at each spark plug wire by using a high output spark tester. Ensure resistance of each spark plug wire is 4000-6000 ohms per foot.
  2. Disconnect and inspect all related ignition system connectors and harness. Clean or repair as necessary, and recheck spark. If still no spark, go to IGNITION COIL POWER SOURCE.
