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. After repairs, go to step 29 . 24. Repair the short to ground in the supply voltage circuit of the starter solenoid. After repairs, go to step 29 . 25. Replace the Starter Relay. After replacement, go to step 29 . 26. Replace the PNP switch. Refer to Automatic Transmission. After replacement, go to step 29 . 27. Replace the Ignition Switch. After replacement, go to step 29 . 28. Replace the starter. Refer to STARTER MOTOR REPLACEMENT . After replacement, go to next step. 29. Operate the system for which the symptom occurred. Did you correct the condition? If yes, system OK. If no, go to step 2 . STARTER SOLENOID CLICKS, ENGINE DOES NOT CRANK 1. Did you perform 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 to the START position. Did the starter solenoid click? If yes, go to next step. If no, go to STARTER SOLENOID DOES NOT CLICK . 3. Inspect the engine and belt drive system for mechanical binding (seized engine, seized generator). Does the engine move freely? If yes, go to next step. If no, go to Engine Mechanical. 4. Test the battery positive cable between the battery and the starter solenoid for high resistance. Did you find and correct the condition? If yes, go to step 8 . If no, go to next step. 5. Test the ground circuit between the battery and the starter motor for a high resistance. Did you find and correct the condition? If yes, go to step 8 . If no, go to next step. 6. Inspect for poor connections at the starter. Did you find and correct the condition? If yes, go to step 8 . If no, go to next step. 7. Replace the Starter. Refer to STARTER MOTOR REPLACEMENT . After replacement, go to next step. 8. Operate the system for which the symptom occurred. Did you correct the condition? If yes, system OK. If no, go to step 2 . ENGINE CRANKS SLOWLY Perform the following checks: z Battery - Battery Inspection/Test. Refer to BATTERY INSPECTION/TEST (NON-HP2) . z Wiring - Inspect the wiring for damage. Inspect all connections to the starter motor, solenoid, battery, and z Engine - Make sure the engine is not seized. Refer to Symptoms in Engine Mechanical.
