Isuzu P'UP (With 1.9L Engine)

  1. Remove distributor cap and ignition module cover. Disconnect ignition coil wire from distributor tower. Hold wire about 1/4" away from distributor coil mounting screw.
  2. Set ohmmeter to "x1" scale. Connect ohmmeter positive lead to White wire terminal and negative lead to Red wire terminal. Remove one ohmmeter lead and check for spark at ignition coil wire. If no spark occurs, ignition module is defective.
NOTE: Do not connect ohmmeter for more than 3 seconds as ignition module may be damaged.
