Replacing the Low-Pressure Fuel Pump Fuse

Model: BMW Serie 7 E66, E67, E68, E65, MK 4 - Years 2001-2008
Part: Pump

If you find that when pressing the ignition button the starter motor turns but the engine does not start, a possible cause could be the lack of fuel supply due to a malfunction of the low-pressure pump, the one submerged in the tank; however, before assuming the worst, which is a complete pump failure, ensure that it is powered, meaning that the corresponding protection fuse has not blown. Therefore, open the rear hood and remove the side cover panel: inside you will find the fuse legend, and at position 75 is the 20 A fuse for the fuel pump; replace it with one of the same capacity and start the engine.
