Release Fuel Line Residual Pressure

Turn the ignition OFF and disconnect the negative battery cable.

Remove the fuel pump fuse (A).

Disconnect the electrical connector from the high-pressure fuel pump.

Connect the negative battery cable.

Run the engine for approximately 20 seconds to reduce the pressure in both the high-pressure and low-pressure lines. The engine may stall during the 20-second period. If not, turn the engine OFF.

Continue the service or repair. Use rags to cover the opening and catch spilled fuel when opening the high-pressure system.

Reinstall/reconnect all components in the reverse order of removal. Start the engine and check that it operates properly, and check that there are no fuel leaks.

After completion, clear the DTC using the GDS diagnostic tool (the procedure described above will set the DTC).
