Starter Solenoid Does Not Click

2002 Chevrolet Impala LSSECTION Starter Solenoid Does Not Click
  1. Did you perform the DIAGNOSTIC SYSTEM CHECK - ENGINE ELECTRICAL? If so, go to next step. If not, go to DIAGNOSTIC SYSTEM CHECK - ENGINE ELECTRICAL  .
  2. Turn the ignition switch to the START position. Does the engine crank? If so, go to INTERMITTENTS  . If not, go to next step.
  3. Install a scan tool. Turn the ignition ON, with the engine OFF. With a scan tool, observe the STARTER RELAY COMMAND parameter in the PCM data list. Turn the ignition switch to the START position. Does the scan tool display ENABLED? If so, go to next step. If not, go to step  12 .
  4. Turn the ignition switch to the START position. Do you hear the Starter relay click? If so, go to step  7 . If not, go to next step.
  5. Turn OFF the ignition. Disconnect the Starter relay. Turn ON the ignition, with the engine OFF. Connect a test light between the battery positive voltage circuit of the Starter relay coil and a good ground. Does the test light illuminate? If so, go to next step. If not, go to step  18 .
  6. Connect a test light between the battery positive voltage circuit of the Starter relay coil and the control circuit of the Starter relay. Turn the ignition to the START position. Does the test light illuminate? If so, go to step  13 . If not, go to step  11 .
  7. Turn OFF the ignition. Disconnect the Starter relay. Connect a test light between the battery positive voltage circuit of the Starter relay switch circuit and a good ground. Does the test light illuminate? If so, go to next step. If not, go to step  19 .
  8. Connect a 30 amp fused jumper between the battery positive voltage circuit of the Starter relay switch circuit and the supply voltage circuit of the starter solenoid. Does the engine crank? If so, go to step  13 . If not, go to next step.
  9. Did the fuse in the jumper open? If so, go to step  20 . If not, go to next step.
  10. Disconnect the supply voltage circuit of the starter solenoid. Connect a test light between the supply voltage circuit of the starter solenoid and a good ground. Does the test light illuminate? If so, go to step  14 . If not, go to step  21 .
  11. Test the control circuit of the Starter relay for an open or a short to battery voltage. Did you find and correct the condition? If so, go to step  26 . If not, go to step  17 .
  12. Test the crank request input circuit of the PCM for an open or a short to ground. Did you find and correct the condition? If so, go to step  26 . If not, go to step  16 .
  13. Inspect for poor connections at the Starter relay. Did you find and correct the condition? If so, go to step  26 . If not, go to step  22 .
  14. Inspect for poor connections at the engine harness connector C112. Did you find and correct the condition? If so, go to step  26 . If not, go to next step.
  15. Inspect for poor connections at the starter solenoid. Did you find and correct the condition? If so, go to step  26 . If not, go to step  23 .
  16. Inspect for poor connections at the ignition switch. Did you find and correct the condition? If so, go to step  26 . If not, go to step  24 .
  17. Inspect for poor connections at the PCM harness connectors. Did you find and correct the condition? If so, go to step  26 . If not, go to step  25 .
  18. Repair an open or high resistance in the battery positive voltage circuit of the Starter relay coil. After repair is complete, go to step  26 .
  19. Repair an open or high resistance in the battery positive voltage circuit of the Starter relay switch. After repair is complete, go to step  26 .
  20. Repair a short to ground in the supply voltage circuit of the starter solenoid. After repair is complete, go to step  26 .
  21. Repair an open or high resistance in the supply voltage circuit of the starter solenoid. After repair is complete, go to step  26 .
  22. Replace the Starter relay. After repair is complete, go to step  26 .
  23. Replace the starter motor. See STARTER MOTOR  . After repair is complete, go to step  26 .
  24. Replace the ignition switch. See IGNITION SWITCH . After repair is complete, go to step  26 .
  25. Replace the PCM. See POWERTRAIN CONTROL MODULE . After replacement is complete, go to next step.
  26. Operate the system in order to verify the repair. Did you find and correct the condition? If so, then system is okay. If not, go to step  2 .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
