Solution

1. Preparation

Tools Required: Wrenches, screwdrivers, fuel pressure gauge, OBD-II scanner, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface, and disconnect the battery to prevent any electrical issues.

2. Inspect Fuel System

Fuel Tank and Lines:
- Visually inspect the fuel tank for any cracks or corrosion.
- Check all fuel lines from the tank to the engine for signs of wear or damage.
Sub-steps:
- If a leak is found, proceed to the next step to replace the damaged line or tank.

3. Fuel Pressure Test

Testing:
- Attach the fuel pressure gauge to the fuel rail or Schrader valve.
- Turn the ignition to the "On" position without starting the engine to check the initial pressure.
Sub-steps:
- Compare the measured pressure to the manufacturer's specifications. If it is low, investigate the fuel pump and filter.

4. Examine Fuel Injectors

Inspection:
- Remove the engine cover to access the fuel rail and injectors.
- Check for fuel leaks around the injectors.
Sub-steps:
- If leaks are detected, replace the faulty injector(s).

5. Check Fuel Filler Neck and Cap

Inspection:
- Inspect the fuel filler neck for rust, cracks, or damage.
- Ensure the fuel cap seals properly and isn't damaged.
Sub-steps:
- Replace the fuel cap if it is found to be faulty.

6. Reassemble and Test

Reconnect any components and the battery.
Start the engine and monitor for any fuel smells or leaks.
Conduct a test drive to ensure the issue is resolved.
