Abstract
In a method of recognizing operating errors in the fuel injection system of an internal combustion engine wherein fuel is supplied by a fuel pump via a common fuel supply line to a number of fuel injectors, the fuel pressure in the common fuel supply line is determined at least at two predetermined points in time between which the pressure should not change when the system is properly operating and an operating error is indicated if a difference in pressure is determined which exceeds a predetermined threshold value.
