Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent accidental electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove any corrosion from the terminals using a wire brush.
- Tighten the battery terminals to ensure a good connection.
Battery Testing:
- If the voltage is below 12.4 volts, charge the battery using a battery charger.
- If the battery fails to hold a charge, replace it with a compatible new battery (Consult owner's manual for specifications).

3. Starter Motor Check and Replacement

Starter Bypass Test:
- Use a jumper wire to connect the starter solenoid terminal to the battery positive terminal. If the starter engages, it may need replacement.
Remove Starter Motor:
- Disconnect electrical connections from the starter motor.
- Remove the starter mounting bolts using a socket set and carefully extract the starter motor.
Install New Starter Motor:
- Position the new starter motor in place and secure it with mounting bolts (torque to manufacturer specifications).
- Reconnect the electrical connections.

4. Final Checks

Reconnect the negative battery terminal.
Ensure all tools and materials are removed from the engine bay.
Perform a visual inspection of the engine compartment for any loose or damaged wires.
