Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative terminal of the battery.

2. Battery Inspection and Replacement

Inspect the battery terminals for corrosion; clean them using a wire brush if necessary.
If the battery is weak or dead, replace it:
- Use a socket set to remove the negative (-) and positive (+) cables from the battery terminals.
- Remove the battery hold-down bracket.
- Lift the old battery out and place the new battery in the tray.
- Reinstall the hold-down bracket and secure it.
- Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Starter Motor and Connections

If the battery is good, check the starter motor:
- Locate the starter, typically near the transmission.
- Disconnect the wiring harness from the starter.
- Use a socket set to remove the starter mounting bolts and the starter from the vehicle.
Bench test the starter:
- Connect the starter directly to a battery to check for functionality.
- If it fails to engage, replace the starter motor.
Reinstall the starter by reversing the removal process.

4. Final Checks

Reconnect all terminals and wiring harnesses securely.
Reconnect the battery's negative terminal.
Attempt to start the vehicle to verify that the issue is resolved.
