Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Check battery connections:
- Clean any corrosion from the terminals using a wire brush.
- Ensure that the battery terminals are tightly secured.
Test battery:
- If the voltage is below 12.4 volts, charge the battery using a battery charger.
- If the battery fails to hold a charge or is older than 3-5 years, consider replacing it.

3. Starter Motor Inspection

Access the starter:
- Remove any components obstructing access to the starter, such as the air intake or battery tray.
Test the starter:
- Locate the starter motor and check the primary wiring for tightness and integrity.
- Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
Replace starter if necessary:
- If no voltage is present or if the starter is faulty, remove the starter motor:
  - Unbolt the starter from the engine block using a socket set.
  - Disconnect the electrical connections (ensure to note the wiring configuration).
  - Install the new starter by reversing the removal steps, ensuring all connections are tight.

4. Final Assembly

Reassemble any components removed for access.
Reconnect the negative battery terminal.
Start the vehicle to check functionality.
