Distributor Pick-Up Coil

  1. Turn ignition off. Using an ohmmeter, check resistance across terminals No. 4 and 5 of ECU connector. See  Figure .  Ohmmeter resistance reading should be 150-900 ohms.
  2. If reading is not within limits, disconnect dual lead connector coming from distributor. Check resistance at dual lead connector to distributor. If reading is not 150-900 ohms, replace pick-up coil assembly in distributor. If reading is within limits, check wiring harness between control unit and dual lead connector.
  3. Connect one ohmmeter lead to a good ground and other lead to either connector distributor. Ohmmeter should show an open circuit. If ohmmeter shows a reading, pick-up coil is grounded in distributor and must be replaced.
