Starter Solenoid Does Not Click

  1. Did you preform the Engine Electrical Diagnostic System Check? If yes, go to next step. If no, go to DIAGNOSTIC SYSTEM CHECK - ENGINE ELECTRICAL .
  2. Turn the ignition switch to the START position. Does the engine crank? If yes, problem is intermittent. If no, go to next step.
  3. Turn the ignition switch to the START position. Does the starter motor relay click? If yes, go to step  11. If no, go to next step.
  4. Is the vehicle equipped with a manual transmission? If yes, go to next step. If no, go to step  7.
  5. Install a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, observe the Clutch Start Switch Signal parameter in the PCM data list while depressing the clutch pedal. Does the scan tool display Released/Applied? If yes, go to step  7. If no, go to next step.
  6. Turn OFF the ignition. Disconnect the PCM harness connector. Connect a test lamp between the Clutch Start Switch Signal of the PCM harness and a good ground. Turn the ignition to the START position while depressing the clutch pedal. Does the test lamp illuminate? If yes, go to next step. If no, go to step  8.
  7. Turn OFF the ignition. Disconnect the PCM harness connector. Connect a test lamp between the crank voltage circuit (starter enable relay control) of the PCM harness and a good ground. Turn the ignition to the START position. Does the test lamp illuminate? If yes, go to step  19. If no, go to next step.
  8. Remove the starter motor relay. Connect a test light from the supply voltage circuit of the starter motor relay coil circuit to ground. With the transmission in park, or clutch pedal depressed, turn the ignition switch to the START position. Does the test light illuminate? If yes, go to next step. If no, go to step  10.
  9. Connect a test light from the supply voltage circuit of the starter motor relay coil circuit to the control circuit of the starter motor relay coil circuit. With the transmission in park, or clutch pedal depressed, turn the ignition switch to the START position. Does the test light illuminate? If yes, go to step  17. If no, go to step  14.
  10. Turn OFF the ignition. Disconnect the Park Neutral Position (PNP) switch. Refer to Automatic Transmissions . Turn ON the ignition, with the engine OFF. Connect a 10 amp fused jumper between the starter motor relay coil control circuits of the PNP switch or clutch pedal position switch. With the transmission in park, or clutch pedal depressed, turn the ignition switch to the START position. Does the test lamp illuminate? If yes, go to step  18. If no, go to step  15.
  11. Turn OFF the ignition. Disconnect the starter motor relay. Connect a test lamp between the battery positive voltage circuit of the starter motor relay switch circuit and a good ground. Does the test lamp illuminate? If yes, go to next step. If no, go to step  23.
  12. Connect a 30 amp fused jumper between the battery positive voltage circuit of the starter motor relay switch circuit and the supply voltage circuit of the starter solenoid. Does the engine crank? If yes, go to step  17. If no, go to next step.
  13. Does the fuse in the jumper open? If yes, go to step  24. If no, go to step  16.
  14. Test the control circuit of the starter motor relay for an open or high resistance. Did you find and correct the condition? If yes, go to step  29. If no, go to step  25.
  15. Test the supply voltage circuit of the starter motor relay coil circuit for an open or high resistance. Did you find and correct the condition? If yes, go to step  29. If no, go to step  21.
  16. Test the supply voltage circuit of the starter solenoid for an open or high resistance. Did you find and correct the condition? If yes, go to step  29. If no, go to step  22.
  17. Inspect for poor connections at the starter motor relay. Did you find and correct the condition? If yes, go to step  29. If no, go to step  25.
  18. If equipped with an Automatic Transmission, inspect for poor connection at the PNP switch harness connector. If okay, perform the Park/Neutral Position Switch Adjustment 4L60-E for AUTOMATIC TRANSMISSION . If equipped with a Manual Transmission , inspect for poor connection at the clutch pedal position switch harness connector. Did you find and correct the condition? If yes, go to step  29. If no, go to step  26.
  19. Inspect for poor connections at the harness connector of the PCM. Did you find and correct the condition? If yes, go to step  29. If no, go to next step.
    20. NOTE: The replacement PCM must be programmed.
  20. Replace the PCM/ECM. Refer to Engine Controls . Is action complete? If yes, go to step  29.
  21. Inspect for poor connections at the ignition switch harness connector. Did you find and correct the condition? If yes, go to step  29. If no, go to step  27.
  22. Inspect for poor connections at the starter solenoid. Did you find and correct the condition? If yes, go to step  29. If no, go to step  28.
  23. Repair the open or high resistance in the battery positive voltage circuit of the Starter Motor relay switch circuit. Did you complete the repair? If yes, go to step  29.
  24. Repair the short to ground in the supply voltage circuit of the starter solenoid. Did you complete the repair? If yes, go to step  29.
  25. Replace the Starter Relay. Did you complete the replacement? If yes, go to step  29.
  26. Replace the PNP switch. Refer to Automatic Transmission . Did you complete the replacement? If yes, go to step  29.
  27. Replace the Ignition Switch. Did you complete the replacement? If yes, go to step  29.
  28. Replace the starter. Refer to STARTER MOTOR REPLACEMENT . Did you complete the replacement? If yes, go to next step.
  29. Operate the system for which the symptom occurred. Did you correct the condition? If yes, system is okay. If no, go to step  2.
