Abstract
In a method for operating a fuel pump of a motor vehicle, the fuel pump is driven by an EC electric motor for conveying fuel in a direction of an internal combustion engine. Accordingly, when no more fuel is required, the EC electric motor of the fuel pump is switched off in such a way that a rotor of the EC electric motor slows down in a defined manner, so that the rotor of the EC electric motor assumes a defined relative position with respect to the stator of the EC electric motor after slowing down.
