A fuel injector control system including a fuel injector, a sensing device configured to provide a transition signal indicative of a fuel injector transition from the closed-state to the open-state, and a controller configured to determine an injector control signal based on the transition signal. The injector control signal closing time can be adjusted base on the transition signal and so compensate for injector opening delay due to, for example, a stuck closed fuel injector, cold temperatures, or low injector drive voltages.
