Remove Engine Cover: Use a socket set to remove bolts securing the engine cover (if applicable).
Disconnect Fuel Injectors: Carefully unplug the electrical connectors from the fuel injectors.
Replace Faulty Injectors: If any injectors are leaking, remove them using a wrench and replace them with new injectors, ensuring proper seating and reinstallation of electrical connectors.

4. Check and Replace Fuel Pressure Regulator

Locate Fuel Pressure Regulator: Typically found on the fuel rail.
Remove Regulator: Disconnect the vacuum line and electrical connector, then unbolt the regulator.
Install New Regulator: Replace with a new fuel pressure regulator, ensuring all connections are secure.

5. Inspect and Replace Fuel Filter

Locate Fuel Filter: Usually found along the fuel line.
Remove Old Filter: Use a wrench to disconnect the filter from the fuel lines.
