Spark Test

Spark Testing:

1. Disconnect #1 ignition wire at the spark plug.
2. Install a spark tester into the end of the spark plug boot.
3. Have an assistant crank the engine over and check for spark at the tester.
4. Repeat this process at each spark plug.
^ If any cylinder does not show spark, check secondary components.
^ If all secondary components test O.K., check primary ignition components.
^ If all cylinders test O.K. and engine doesn`t start, inspect for fouled spark plugs and clean or replace as necessary.
5. If no faults are found in the above tests, proceed to COMPUTERIZED ENGINE CONTROLS for further diagnosis.
