Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-steps:
- Disconnect the negative terminal from the battery.
- Clean the battery terminals using a wire brush and a solution of baking soda and water.
- Reconnect the terminals and ensure they are tight.

3. Starter Replacement (if necessary)

Sub-steps:
- Disconnect the battery negative terminal again.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove any components obstructing access to the starter, such as the air intake duct.
- Unbolt the starter from its mounting bracket (typically two or three bolts).
- Disconnect the electrical connectors from the starter solenoid.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.
- Torque the starter bolts to the manufacturer's specifications (typically 20-30 ft-lbs).

4. Final Assembly

Reinstall any components removed for access.
Reconnect the negative battery terminal.
Check all connections and ensure everything is secured before starting the vehicle.
