Ignition System Starting Test

  1. Remove coil wire from distributor cap. Hold end of wire 1/4" away from good engine ground. Have assistant crank engine, while you watch for spark at secondary wire. Spark should be constant and bright Blue.
  2. If there is a good spark, continue cranking engine while slowly moving secondary wire away from ground. Look for arcing at coil tower. If arcing occurs, replace coil. If spark is weak or not constant, or if there is no spark, proceed to FAILURE TO START TEST.
  3. If spark is good and there is no arcing at the coil tower, secondary voltage is satisfactory. Ensure spark is reaching spark plugs by checking distributor rotor, cap, spark plug wires and spark plugs.
  4. If all of these components check okay, ignition system is not at fault. Check fuel system or engine for mechanical damage.
