Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, fuel pressure gauge, safety goggles, and gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical hazards.

2. Inspect Fuel Lines

Use a socket set to remove any covers obstructing access to the fuel lines.
Visually inspect the fuel lines for cracks, leaks, or loose connections.
If damage is found, replace the affected fuel line with a new one, ensuring proper fittings.

3. Check Fuel Tank

Safely lift the vehicle using jack stands and remove the rear underbody shield if necessary.
Inspect the fuel tank for any signs of damage or corrosion.
If corrosion is present or if there are punctures, replace the fuel tank.

4. Examine Fuel Injectors

Remove the engine cover if applicable to access the fuel injectors.
Check for fuel leakage around the injectors using a cloth or paper towel.
If leakage is detected, replace the faulty injector(s).

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail according to the manufacturer’s specifications.
Start the engine and observe the pressure readings; compare them to the specifications in the service manual.
If pressure is below specifications, check the fuel pump and replace if necessary.

6. Reassemble and Reset

Reinstall any removed components in reverse order.
Reconnect the negative battery terminal.
Clear any stored error codes using the OBD-II scanner.
