Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, jumper cables.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect the battery terminals and clean any corrosion using a wire brush.
2. Securely reconnect the battery terminals.
3. If the battery voltage is low, replace the battery with a new one rated for the vehicle.
  - Torque for battery terminal bolts: 10-12 ft-lbs.

3. Starter Testing and Replacement

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Use a multimeter to check for voltage at the starter’s positive terminal when the key is turned.
3. If no voltage is present, check the starter relay and replace if faulty.
4. If voltage is present and the starter does not engage, remove the starter:
  - Disconnect electrical connectors.
  - Remove the mounting bolts.
  - Replace with a new starter, ensuring it is properly aligned and secured.
  - Torque for starter mounting bolts: 15-20 ft-lbs.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the ignition switch cover.
2. Inspect wiring connections for damage or loose connections.
3. Test the ignition switch using a multimeter to ensure continuity when turned.
4. Replace the ignition switch if it fails the continuity test.
