Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Torque wrench

2. Test and Replace Battery (if needed)

Use the multimeter to measure the battery voltage. If below 12.4V, proceed with replacement.
Remove the negative terminal (10mm socket) followed by the positive terminal.
Unbolt the battery hold-down bracket (if applicable) and lift the battery out.
Install the new battery in reverse order, ensuring terminals are clean and connections are tight.
Torque battery terminals to manufacturer specifications.

3. Inspect and Replace Starter Motor (if needed)

If the starter motor is suspected, remove the negative battery terminal again for safety.
Disconnect wiring harness from the starter motor and remove the mounting bolts using a socket set.
Remove the starter motor and inspect it visually for damage.
If defective, install a new starter motor and torque bolts to manufacturer specifications.
Reconnect the wiring harness and battery terminals.

4. Check Fuel System (if needed)

If the fuel pump is non-functional, access the fuel pump relay and fuse.
Replace any blown fuses and test the relay for continuity with a multimeter.
If the pump is faulty, remove the fuel pump assembly from the tank (ensure fuel is drained).
Replace the pump and reassemble everything, ensuring no leaks are present.
