Fuel supply system for an internal combustion engine, especially a motor vehicle

A computer program product having a program, the computer program product comprising:

• a carrier readable by a computer and said program being stored on said carrier;
• and,
• when executed by the computer, said program being suitable for carrying out a method for starting an internal combustion engine including a starter, an internal combustion engine of a motor vehicle, the engine including an ignition, pressure store and injection valves for injecting fuel directly into the engine, the method including the steps of:
• providing an electrical fuel pump and an electrical high pressure pump connected to said electrical fuel pump downstream thereof for pumping the fuel into said pressure store;
• first switching said electrical fuel pump and said electrical high pressure pump on together with said ignition in order to generate a pressure in said pressure store adequate for the injection of the fuel;
• and,
• then, switching said starter on after a time duration after said electric fuel pump and said electrical high pressure fuel pump are switched on.
