Abstract

In a method for controlling a fuel injection system of an internal combustion engine with at least one combustion chamber, wherein the fuel injection system comprises a high pressure pump, whose flow rate is controllable, a control parameter of the high pressure pump is evaluated during the operation of the internal combustion engine. Said control parameter makes a detection of a bottleneck with the high pressure pump with respect to fuel quantity possible.
