Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Fuel System

Check Fuel Pump Relay:
- Locate the relay in the fuse box.
- Swap with a similar relay to test or use a multimeter to check for continuity.
Test Fuel Pump:
- Reconnect the battery.
- Turn the ignition to the "ON" position (do not start).
- Listen for a humming sound from the fuel tank, indicating the pump is functioning.
Inspect Fuel Lines:
- Visually inspect fuel lines for cracks or leaks.
- Repair or replace any damaged lines.

3. Check Electrical Connections

Battery Inspection:
- Use a multimeter to check the battery voltage; it should be around 12.6 volts.
- Clean and tighten battery terminals if corroded or loose.
Ignition System Check:
- Remove spark plugs and inspect for wear or fouling.
- Test ignition coils with a multimeter to ensure they are within specifications.

4. Reassemble and Test

Reconnect all components and ensure everything is secure.
Reconnect the negative battery terminal.
Attempt to start the vehicle.
