WARNING:
When using a remote starter switch or jumper wire, be sure the ignition switch is in the Off position and the transmission is in Park with the parking brake control fully applied.
- Verify starter is installed properly. Ensure bolts are tight. If starter is mounted properly, go to next step. If starter is not mounted properly, repair as necessary.
- Turn ignition switch to LOCK position. Connect remote starter switch between starter solenoid terminal "B" (positive battery cable connection) and terminal "S" (Yellow/Light Blue wire). See Figure . Engage starter motor and verify noise is coming from starter motor. If noise is coming from starter motor, go to next step. If noise is not coming from starter motor, diagnose engine mechanical concern. See appropriate article in ENGINES.
- Remove starter motor. See STARTER MOTOR under REMOVAL & INSTALLATION. Inspect flywheel ring gear for wear or damage. See Fig 1 . If ring gear is okay, replace starter motor. If ring gear is worn or damaged, replace ring gear and inspect starter drive gear. If drive gear is also damaged, replace starter motor.
