Abstract
A fuel injection system includes an injector control module, a current detection module, and a position determination module. The injector control module controls current through a solenoid of a fuel injector for a predetermined period. The current detection module measures an amount of current through the solenoid after the predetermined period. The position determination module determines whether the fuel injector injected fuel during the predetermined period based on when the amount of current through the solenoid is less than or equal to a predetermined current.
