Testing Spark At Coil

1994 Plymouth Grand Voyager Base, 31THSECTION Testing Spark At Coil
  1. Remove coil wire from distributor cap. Hold end of cable approximately 1/2" (13 mm) from engine ground. Crank engine and check for spark from coil wire. Spark should be present and constant.
  2. If spark is present and constant, continue cranking engine. Slowly move coil wire away from ground. As coil wire is moved away from ground, check for arching at coil tower. If arching at coil tower is present, replace coil.
  3. If spark is good and no arching is present, secondary ignition system is producing necessary voltage. Ensure spark reaches spark plugs by checking condition of rotor, cap, spark plug wires and spark plugs. Repair or replace secondary ignition components as necessary. If ignition system components are in good condition, ignition system is okay. If vehicle still fails to start, proceed to NO-START TEST. Also refer to TESTS W/CODES - 2.5L TBI article in the ENGINE PERFORMANCE section.
