Check For Spark

Turn ignition off. Disconnect a spark plug wire. Connect Spark Tester (D81P-6666-A) to disconnected spark plug wire. Crank engine and observe spark tester. If spark is a continuous strong Blue spark, ICM circuit is okay. If spark is not a continuous strong Blue spark, go to next step.
