Intermittent Problems
- Attach modified spark plug, in turn, to 2 different spark plug wires and crank engine. If no spark, repeat previous test, System Voltage Check with Modified Spark Plug.
- If spark occurs from one or both wires, check pick-up coil resistance for 500-1500 ohms. If not to specifications, replace pick-up coil. If okay, check for dwell increase from a high to low RPM.
- If dwell increases, check fuel system, spark plug wires, distributor cap and spark plugs. If no increase occurs, replace electronic module.
