Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery cable to prevent electrical shock or shorts.

2. Battery Inspection

Tools Required: Multimeter, wire brush, socket set
Clean battery terminals using a wire brush to remove any corrosion.
Reconnect the battery terminals securely.
If the battery voltage is low, replace the battery with a new one, ensuring proper terminal connections.

3. Starter Replacement (if needed)

Tools Required: Socket set, torque wrench, ratchet, screwdrivers
Remove any components obstructing access to the starter (e.g., air intake duct).
Disconnect the electrical connectors from the starter motor.
Remove the starter mounting bolts and carefully extract the starter from the vehicle.
Install the new starter in reverse order, ensuring bolts are torqued to manufacturer specifications (typically around 20-25 ft-lbs).
Reconnect all electrical connectors securely.

4. Testing

Reconnect the negative battery cable.
Start the vehicle to verify that the issue has been resolved.
