The fuel pressure check involves connecting a fuel pressure gauge to the Schrader valve test port on the fuel rail, relieving the fuel pressure, starting the engine and noting the gauge reading, and comparing it with the proper pressure specifications.

To remove the high-pressure fuel pump, you need to follow these steps: 1. Relieve the fuel system pressure and disconnect the electrical connector. 2. Disconnect the intake air ducting and remove the charge air cooler inlet pipe for better access. 3. Loosen the fuel line fitting at the injector rail and the inlet/outlet lines at the high-pressure pump. 4. Remove the bracket and fiber pump cover by removing the three bolts. 5. Disconnect the flexible fuel line and remove the metal fuel lines from the high-pressure pump. 6. Finally, remove the old fuel pump mounting bolts and discard them, replacing them with new ones.

Installation is the reverse of removal.
