What is the preliminary check for the fuel pump and how do you perform a pressure check on Mercedes-Benz C350?

The fuel pump is contained in the fuel tank. To test its operation, with the ignition key in an ON position (not START) listen for low whirring sound which indicates pump working. If the sound is not heard from inside the car, thread off the fuel filler cap and have someone turn the ignition ON while you listen close to the fuel filler. If the pump fails to fire, check the fuel pump fuse and relay in the fuse and relay box on the trunk's left side. If the above components are OK, check the wiring of the fuel pump. If all checks out and pump is running all the time with the ignition in the ON position, then the Powertrain Control Module (PCM) may be defective and should be evaluated by a qualified service department. For fuel pressure test, fuel pressure gauge that can measure high pressure is required and adapter for the Schrader service valve on fuel rail. Start by getting the fuel system pressure out. Remove the Schrader valve cap and attach the gauge to fuel rail. Start the engine and check the pressure on the gauge and see if it falls within the specified range. If the pressure is low but below specifications, look for restrictions in the fuel system, such a check the fuel inlet strainer that is located at the base of the fuel pump/fuel level sensor module and cannot be replaced separately. If the pressure is above specifications, then the fuel pressure regulator, an integral part of the fuel filter, which is located behind the left chamber of the fuel tank, should be replaced.
