When troubleshooting a starting circuit malfunction, check battery cable clamps, cables, battery condition, starter solenoid wiring, connections, and mounting bolts. Also, ensure shift lever is in PARK or NEUTRAL. If starter doesn't operate when ignition is turned to START, check for battery voltage to solenoid and test starting system circuit. If starter turns over slowly, check cranking voltage and current drawn from battery. If values are incorrect, replace starter. If starter receives voltage but doesn't activate, remove and check starter/solenoid assembly on bench, ensuring engine isn't seized. If solenoid plunger extends and rotates pinion drive, assembly is working properly.

Remove the right front wheel well splash shield.

If the starter motor does not operate, the following steps should be taken: 1. Check for battery voltage to the solenoid. 2. Test the starting system circuit.

To assess the adjustment of the PNP switch, verify whether the starter engages when the ignition switch is turned to the start position.

The initial steps for removing and replacing a starter motor include:Disconnecting the cable from the negative terminal of the battery.Raising the vehicle and securing it on jackstands.

Before assuming the starter is the problem, it is important to check the following items: 1. Clean and tight battery cable clamps where they connect to the battery. 2. Condition of the battery cables. 3. Battery's condition. 4. Starter solenoid wiring and connections. 5. Starter mounting bolts for tightness. 6. Ensure the shift lever is in PARK or NEUTRAL.

If the starter is receiving voltage but does not activate, the following steps should be taken: 1. Remove and check the starter/solenoid assembly on the bench. 2. Ensure that the engine is not seized. 3. If the solenoid plunger extends and rotates the pinion drive, the starter/solenoid assembly is working properly.

Remove the right front wheel well splash shield.

Remove the starter motor mounting bolts and remove the starter motor.

Disconnect the battery cable and starter control cable from the starter motor solenoid terminals.

Remove the starter solenoid shield and the transmission bell housing bolt (Remove the transmission bellhousing cover bolt).- Remove the starter mounting bolts (Remove the starter mounting bolts).- Carefully lower the starter with the terminals facing toward the front of the vehicle.- Disconnect the wires from the terminals on the starter solenoid (Remove the nuts and disconnect the battery cable and the solenoid terminal from the starter motor) and remove the starter from the vehicle.

Disconnect the battery cable and starter control cable from the starter motor solenoid terminals.

If the starter motor doesn't engage when voltage is present at the solenoid, remove the starter from the engine and perform a bench test to identify potential issues.

Disconnect the cable from the negative battery terminal.

If the starter turns over slowly, the following steps should be taken: 1. Check the starter cranking voltage. 2. Check the current drawn from the battery. 3. If the starter cranking amp values are not within the correct range, replace the starter with a new unit.

If the starter is receiving voltage but does not activate, the following steps should be taken: 1. Remove and check the starter/solenoid assembly on the bench. 2. Ensure that the engine is not seized. 3. If the solenoid plunger extends and rotates the pinion drive, the starter/solenoid assembly is working properly.
