Abstract

A method is provided for starting an internal combustion engine which includes a starter, an ignition, pressure store and injection valves for injecting fuel directly into the engine. An electrical high pressure pump is connected to an electrical fuel pump downstream thereof for pumping the fuel into the pressure store. The electrical fuel pump and the electrical high pressure pump are first switched on together with the ignition in order to generate a pressure in the pressure store adequate for the injection of the fuel. Then, the starter is switched on after a time duration after the electric fuel pump and the electrical high pressure fuel pump are switched on.
