Relieving Fuel System Pressure


Locate the fuel pump relay in the engine compartment fuse block at location K4/C-1051. Remove the fuel pump relay. Start the engine and allow it to idle until it stalls. Crank the engine for 5 seconds to ensure fuel supply manifold pressure is released. When vehicle service is complete, reinstall the fuel pump relay and turn the ignition on to pressurize the fuel system. Start the vehicle and check the system for leaks.

Remove the Schrader valve cap from the fuel rail. Install fuel pressure gauge no. 310-012. Slowly open the manual valve to release the pressure, using a container to catch any residual fuel. When servicing is complete, remove the gauge, install the cap and start the engine. Check for leaks.
