Abstract
In a method for operating a fuel pump of a motor vehicle, the fuel pump is driven by an electric motor in such a way that the fuel pump is driven by an energized electric motor in a defined rotational direction in order to feed fuel in the direction of an internal combustion engine. Accordingly, if it is detected that the fuel pump is blocked, the rotational direction of the fuel pump is changed at least once for a specific time period.
