Disclosed is a method of operating a fuel injection system of an internal combustion engine by controlling the injection timing. The injection system comprises a fuel injector, hydraulically connected to a fuel rail. The method comprises determining a nominal energizing time indicative of a nominal fuel quantity to be injected into the cylinder, determining a first energizing time correction as a function of the nominal energizing time and a fuel rail pressure and determining a second energizing time correction as a function of the first energizing time correction, the fuel rail pressure, and a fuel temperature. A target energizing time is calculated by adding the nominal energizing time and the first and second correction times. The fuel injector is then energized for the target energizing time to inject the nominal fuel quantity.
