System Spark Check
- If vehicle will not start, check for secondary voltage. Remove coil high tension wire from distributor cap. Hold wire approximately 1/4" (6 mm) from engine ground, using insulated pliers.
- Crank engine and check for a constant blue spark at gap to ground. If there is a good spark, check distributor cap, rotor, spark plug wires, spark plugs, fuel system and engine mechanical components. If there is no spark or only a very weak spark, perform the following checks.
