INSPECTION
1. Disconnect high-tension code from spark plug.
2. Remove the spark plug.
3. Connect the spark plug to a high tension code.
4. Hold the spark plug with insulated pliers 5~10mm from a ground.
5. Crank the engine and verify that there is a strong blue spark.
If there is no spark, inspect the following points.
Step Inspection Action
