JC30 - Check For Spark During Crank - KOEC

- Using a Neon Bulb Spark Tester (Special Service Tool DS9P-6666-A) or Air Gap Spark Tester (D81P-6666-A). Check for spark at all spark plug wires while cranking.

- When using the spark plug firing indicator, place the grooved end as close as possible to the plug boot. Very weak or no flashing may be caused by a fouled plug.

- Was spark consistent on all spark plug wires (one spark per crankshaft revolution?)

YES -- Go to Symptom Flowcharts. The ignition system is OK. Testing and Inspection

NO -- Go to JC31. Spark fault. JC31 - Check For Spark at Right Spark Plug Wires During Crank
