Module-To-Coil Wire Check

  1. Disconnect control module 4-wire connector and ignition coil connector. Connect one ohmmeter lead to distributor base and the other to "TACH" terminal of ignition coil connector. Measure resistance and reconnect all connectors.
  2. If resistance is greater than 1 ohm, replace control module. If resistance is 1 ohm or less, inspect wiring harness between control module and ignition coil.
