Sub-steps:
- Remove the engine cover if applicable.
- Unplug the electrical connectors to the fuel injectors.
- Remove the fuel rail bolts and lift the rail to access the injectors.
- Inspect for any leaks; replace any faulty injectors.
- Reassemble in reverse order, ensuring all connections are secure.
Tools Required: Socket set, torque wrench.

5. Inspect Fuel Pressure Regulator

Sub-steps:
- Locate the fuel pressure regulator (typically on the fuel rail).
- Disconnect the vacuum line and check for fuel leakage.
- Replace the regulator if any fuel is present in the vacuum line.
- Reconnect all lines and secure properly.
Tools Required: Pliers, socket set.
