Solution

1. Preparation

Ensure the vehicle is in "Park" (automatic) or "Neutral" (manual).
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Sub-steps:
1. Clean the battery terminals using a wire brush and a solution of baking soda and water if corrosion is present.
2. Reconnect the battery terminals securely.
3. If the battery voltage is low, recharge or replace the battery as needed.

Tools Required: Wire brush, baking soda, multimeter

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor; typically found near the transmission.
2. Disconnect the electrical connectors from the starter motor.
3. Use a multimeter to check for voltage at the starter motor terminals when the key is turned to the start position.
4. If no voltage is detected or if the starter is faulty, remove the starter motor using a socket set (usually requires a 10mm or 13mm socket).
5. Install the new or refurbished starter motor, securing it with the bolts to the specified torque (usually around 15-20 ft-lbs).
6. Reconnect the electrical connectors to the starter.

Tools Required: Socket set, multimeter

4. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Disconnect the ignition switch connector and test for continuity using a multimeter while turning the key.
3. If the ignition switch is defective, replace it by removing the retaining screws and installing the new switch.
