Abstract
A fuel injection system for a vehicle propulsion system includes an injector driver module that applies power to a fuel injector of an engine in the vehicle propulsion system for a fuel injection event, a voltage measuring module that measures first and second voltages at first and second electrical connectors of the fuel injector, a voltage difference module that determines a difference between the first and second voltages, and a diagnostic module with a pattern based neural network that determines whether the fuel injector injected fuel based on the difference between the first and second voltages.
