Safety Warnings: Fuel can be under pressure; relieve the pressure by removing the fuel pump fuse and starting the engine until it stalls.

3. Check Fuel Injectors

Sub-steps:
- Locate the fuel injectors on the engine.
- Inspect for any fuel leakage around the injector seals.
- If leaking, remove the fuel rail and replace the faulty injector(s).
Tools Required: Socket set, fuel injector puller.
Safety Warnings: Ensure all fuel is contained during removal to avoid fire hazards.

4. Examine Fuel Tank

Sub-steps:

- If damage is found, drain the tank and replace it with a new one.
Tools Required: Jack stands, drain pan, socket set.
Safety Warnings: Ensure the vehicle is on a stable surface and the fuel is handled safely.

5. Test Fuel Pressure Regulator

Sub-steps:
- Locate the fuel pressure regulator (usually near the fuel rail).
- Use a fuel pressure gauge to check the pressure readings against manufacturer specifications.
- If out of range, replace the regulator.
Tools Required: Fuel pressure gauge, socket set.
Safety Warnings: Fuel pressure can be dangerous; use caution when testing.
