Control Module Check
- Be sure all ignition system wires and connectors are properly connected. Disconnect coil-to-distributor high voltage wire at the distributor. Hold wire about 1/4" (5-6 mm) from a good engine ground, using insulated pliers. See Fig 1.
- Crank engine and check for sparks at gap to ground. If previous tests have disclosed no problem and no spark exists at gap, replace control module.
