Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and basic hand tools.
Ensure the vehicle is in a well-ventilated area and parked on a flat surface.

2. Battery Replacement (if faulty)

Disconnect the negative terminal of the battery first, followed by the positive terminal.
Remove the battery hold-down bracket using the socket set.
Carefully lift the old battery out of the vehicle.
Install the new battery, ensuring the correct orientation.
Reattach the positive terminal first, followed by the negative terminal, and tighten securely.

3. Starter Motor Inspection/Replacement (if faulty)

Disconnect the battery to prevent electrical shorts.
Remove the starter motor connections (positive and solenoid).
Unbolt the starter motor from its mounting using the socket set.
Inspect the starter gear for wear; replace if damaged.
Install the new starter motor, ensuring all connections are secure.
Reconnect the battery and test the starter operation.

4. Fuel System Check (if applicable)

Inspect the fuel pump relay and fuses for continuity.
If the fuel pump is faulty, replace it by accessing the fuel tank (may require lifting the vehicle).
Replace the fuel filter if clogged.
