Starter Does Not Crank

  1. Check Voltage To Solenoid "B" Terminal

    Turn ignition off. Measure voltage between ground and "B" terminal on starter solenoid. If battery voltage exists, go to next step. If battery voltage does not exist, repair cable or ground connections. Restore electrical connections and check system operation.

  2. Check Power To Ignition Switch

    Turn ignition off. Disconnect ignition switch harness connector (at ignition switch). Measure voltage between ground and Yellow wire at ignition switch harness connector. If battery voltage exists at Yellow wire, go to next step. If battery voltage does not exist at Yellow wire, repair open wire in question. Restore electrical connections and check system operation.

  3. Check Ignition Switch Operation

    Reconnect ignition switch. While holding ignition switch in START position, measure voltage between ground and White/Pink wire at ignition switch harness connector. If battery voltage exists, go to next step. If battery voltage does not exist, replace ignition switch. Restore electrical connections and check system operation.

  4. Check Voltage To Transmission Range Sensor

    Disconnect Transmission Range (TR) sensor harness connector. While holding ignition switch in START position, measure voltage between TR sensor terminal No. 10 (White/Pink) and ground. See Fig 1 . If battery voltage exists, go to next step. If battery voltage does not exist, repair open White/Pink wire between fuse panel and TR sensor. Restore electrical connections and check system operation.

  5. Check Transmission Range Sensor Operation

    Reconnect TR sensor. Place transmission selector in Park or Neutral. While holding ignition switch in START position, backprobe TR sensor terminal No. 12 (Red/Light Blue wire). See Fig 1 . If battery voltage exists, go to next step. If battery voltage does not exist, replace TR sensor. Restore electrical connections and check system operation.

  6. Check Voltage To Starter Relay

    Remove starter relay from engine compartment fuse/relay box. Place transmission in Park and hold ignition switch in START position. Measure voltage between starter relay connector terminal No. 86 (Red/Light Blue wire) and ground. See Fig 2 . If battery voltage exists, go to next step. If battery voltage does not exist, repair open Red/Light Blue wire. Restore electrical connections and check system operation.

  7. Check Voltage To Starter Relay

    Measure voltage between ground and starter relay harness connector terminal No. 30 (Yellow wire). See Fig 2 . If battery voltage exists, go to next step. If battery voltage does not exist, check fuse No. 2 (30-amp). If fuse is okay, repair open Yellow wire. Restore electrical connections and check system operation.

  8. Check Voltage To Starter Motor

    Disconnect Yellow/Light Blue wire from starter solenoid "S" terminal. With transmission on Park and ignition switch in START position, measure voltage between ground and Yellow/Light Blue wire. If battery voltage exists, replace starter relay. If battery voltage does not exist, repair open Yellow/Light Blue wire. Restore electrical connections and check system operation.
