Electronic Ignition System: Spark
- Crank engine. Using a high output spark tester, test for a strong Blue spark at each secondary ignition plug wire. If spark is not as described, go to next step.
- Verify resistance of each spark plug wire is not more than 25,000 ohms. Unplug and inspect all related ignition system connectors and harness. Clean or repair as necessary, and recheck spark. If strong Blue spark is still not present, go to IGNITION COIL POWER SOURCE .
