A procedure to recognize a depressurized fuel system of a motor vehicle with an internal combustion engine that includes a parameter characterizing the fuel system temperature is acquired when turning off the internal combustion engine; a parameter characterizing the fuel system temperature is acquired in the immediately subsequent driving cycle when starting the internal combustion engine; and from the difference between the shut-down temperature and the starting temperature, the pressure in the fuel system is inferred.
