[QUOTE="jarance, post: 520426, member: 21"] Can you describe the sound from the pump? A proper way to check the condition of the fuel pump is to check the pressure at the fuel rail. The mechanic will connect a pressure gauge at fuel rail. Pressure should be constant cos excess fuel is return via the pressure regulator located at the end of the fuel rail. If the pressure is not up to expected value of 3 to 3.5 bar, then the pump may need to be changed. However, sometime, the problem could be due to a chocked or dirty fuel filter. [/QUOTE]
