Run Circuits Check
- Remove ignition coil wire from distributor cap and install spark tester on wire. Turn ignition switch from "OFF" to "RUN" to "OFF" several times. Sparks should occur at tester gap each time switch goes from "RUN" to "OFF" position. Remove spark tester and reconnect coil wire to distributor cap.
- If sparks occur, check distributor cap, adapter (if equipped) and rotor for cracks, carbon tracking or lack of silicone compound. Also check for roll pin retaining reluctor to sleeve in distributor shaft and check that Orange and Purple wires are not crossed between distributor and control module.
- If no sparks occurred in step 1) proceed to "CONTROL MODULE VOLTAGE CHECK ".
