A method is described for operating a fuel injection system, in particular of an internal combustion engine, in which fuel under pressure is made available in a pressure reservoir and a fuel pressure prevailing in the pressure reservoir is ascertainable with the aid of a pressure sensor. Fuel is removed from the pressure reservoir over a predefinable pressure reduction time period, measured pressure values are ascertained (determined) with the aid of the pressure sensor at least two different points in time during the pressure reduction period, and an actual fuel pressure at the beginning of the pressure reduction period is inferred from the measured pressure values ascertained (determined) during the pressure reduction period. |
