Claim:
1. A fuel system for an internal combustion engine, the system comprising: a fuel accumulator positioned to receive a fuel flow; a sensor adapted to detect a fuel pressure in the fuel accumulator and to transmit a pressure signal indicative of the fuel pressure in the fuel accumulator; a plurality of fuel injectors, each fuel injector operable to deliver a quantity of fuel from the fuel accumulator to one of a plurality of combustion chambers; and a control system adapted to generate a control signal to command a stop of the fuel flow to the accumulator, to determine an actual termination of fuel flow to the accumulator based on the pressure signal, to determine a command delay from a transmission of the control signal to the termination of fuel flow using at least one of RPM data of the engine and crank angle data of the engine, and to adjust an operating parameter of at least one of the plurality of fuel injectors based on the analysis of the pressure signal.
