Ignition Checks: Spark
- Using an ohmmeter, ensure spark plug wire resistance of each wire is 3000-6700 per foot. Check for a strong Blue spark at coil wire and each spark plug wire by holding wire terminal 5/16" from ground while cranking engine.
- Disconnect and inspect all related ignition system connectors and harness. Clean or repair as necessary and recheck spark. If okay, go to next step.
