A system and method for controlling an injector in a fuel cell system. The method provides a variety of injector pulse widths for at least one predetermined duty cycle and determines an injector close time for each of the variety of injector pulse widths. The method also determines an error for the at least one predetermined duty cycle based on each of the provided injector pulse widths and uses the injector pulse width with the lowest error for the at least one predetermined duty cycle.
