The fuel pump operation check involves listening for the soft whirring sound made by the fuel pump when the ignition key is turned ON. If the pump does not come on, check the fuel pump fuse, relay, and wiring. If they are all okay, the fuel pump is likely defective. Connect a gauge to the test port on the fuel rail. Relieve the fuel pressure, start the engine, and note the reading. The reading should be compared with the proper pressure specifications. If the pressure is not within specifications, the fuel system should be checked for restrictions and the fuel pump module may need to be replaced. Verify that the fuel pressure does not lose more than 8 psi for five minutes after the engine is turned off and to check for any fuel leaks.

Disconnect the cable from the negative battery terminal.

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.

Disconnect the fuel level sensor connector at the top of the module.

The fuel pump inlet strainer should be clean.
