ABSTRACT:
A fueling system for an internal combustion engine. The system has a voltage booster and a fuel injector. The voltage booster is operatively coupled to the injector to selectively drive the injector. A method includes determining compliance of a booster voltage with a threshold. The method further includes diagnosing fuel system error based upon the determining compliance.
