A control method of a fuel injection system is provided. The method includes receiving a set value for a target pressure in an injection rail that provides fuel to the engine and receiving an output demand representing a target amount of fuel to be injected from the injection rail per engine cycle. A control mode signal is received and an actual pressure in the injection rail is measured. A control mode is selected based on the control mode signal. A fuel pump flow demand for a fuel pump connected to the injection rail is determined based on a difference between the set value for the target pressure and the actual pressure, based on the output demand, and based on the selected control mode. The fuel pump is then operated according to the fuel pump flow demand and based on the selected control mode to provide fuel to the injection rail.
