Component Testing
- Use the Spark Plug Inspection procedure to verify the integrity of the spark plugs. Refer to Spark Plug Inspection . Replace the spark plug if necessary.
- Use the J 26792 to verify the output of each ignition module/coil. If no spark is detected across the gap of the spark plug tester, then replace the ignition module/coil assembly.
IMPORTANT:
An erratic or weak spark is considered a no spark condition.
