Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper wires, and safety gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Inspect Battery
- Remove battery terminals (negative first, then positive).
- Clean terminals with a wire brush if corroded.
- Reconnect terminals securely.
Test Battery
- Use the multimeter to check voltage. If below 12.4 volts, recharge or replace the battery.
Replace Battery (if needed)
- Use a new battery of the same specifications.
- Install the new battery: connect positive terminal first, then negative.

3. Starter Motor Check

Bypass Starter Motor
- Disconnect the wiring harness from the starter.
- Use jumper wires to connect the battery directly to the starter terminal (be careful to not touch grounded parts).
- If the starter engages and turns the engine, the starter is functioning; if not, it may need replacement.

4. Fuel System Inspection

Check Fuel Pump
- Turn the ignition key to the "ON" position without starting the engine.
- Listen for the fuel pump's whirring sound from the fuel tank.
- If silent, check the fuel pump fuse and relay; replace if necessary.
Check Fuel Lines
- Inspect fuel lines for any leaks or blockages.

5. Final Checks

Once all components are checked/repaired, attempt to start the vehicle.
If the vehicle starts, monitor for any unusual sounds or warning lights.
