Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner.
Ensure the vehicle is parked on a level surface, and the engine is off. Disconnect the negative battery terminal to ensure safety.

2. Battery Replacement (if necessary)

Sub-steps:
1. Remove the negative battery terminal (10mm socket).
2. Remove the positive battery terminal (10mm socket).
3. Unscrew and remove any retaining brackets securing the battery.
4. Lift out the old battery and install the new one, ensuring correct polarity.
5. Reattach the positive terminal first, followed by the negative terminal.
6. Tighten all connections securely.

3. Fuel System Inspection

Sub-steps:
1. If the fuel pump is not operating, locate the fuel pump relay in the fuse box.
2. Replace the relay if it appears faulty.
3. If necessary, replace the fuel filter and inspect for any leaks in the fuel lines.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal again.
2. Remove any components obstructing access to the starter motor.
3. Disconnect the wiring harness and remove the mounting bolts (typically 13mm or 15mm).
4. Install the new starter motor in reverse order of removal and reconnect wiring.
