Abstract

A fuel supply system (1) for an internal combustion engine, especially of a motor vehicle, is described which is provided with an accumulator (2) and a pump (6, 10). Fuel can be supplied to the accumulator (2) with the pump (6, 10). A control apparatus (16) is provided for controlling (open loop and/or closed loop) the pressure in the accumulator (2) by a pressure control valve (4). With the control apparatus (16), the pressure control valve (4) can be closed when the engine is intended to be started but no rotational movement is yet present.
