Fuel System, Filling and Bleeding

Fuel System, Filling and Bleeding


After installing the high pressure pump, it must be filled with fuel before starting the engine for the first time (never allow the pump to run dry).

• When installing the high pressure pump, make sure that no dirt enters the fuel system.

• Only remove the sealing plugs right before installing the fuel lines.

• The fuel tank must be filled.

To fill the high pressure fuel pump with fuel, proceed as follows:

- Turn on the ignition.

- Connect the vehicle diagnostic tester and perform the guided function "Vent Fuel System".

• The fuel pump is activated for 3 minutes.

- Then, start the engine.

- After filling the fuel system, allow the engine run at a moderate speed for a few minutes and then turn it off.

- Check the fuel system for leaks.

- Check the Diagnostic Trouble Code (DTC) memory and erase any DTC memory entries, if necessary.

- Drive the vehicle on a 20 km (12.43 mile) road test using full throttle at least one time. Then check the high pressure area one more time for leaks.

• If there is still air in the fuel system, the engine may switch to emergency mode during the road test. Turn off the engine and erase the DTC memory. Then continue the road test.

- Check the DTC memory again.
