Abstract

An injector relay diagnostic system is provided. The system comprises a first fuel injector, a first electrical relay disposed between an electrical potential and the first fuel injector, wherein the first electrical relay is configured to connect the first fuel injector to the electrical potential upon receipt of a first control signal, and a control module configured to transmit the first control signal to the first electrical relay, receive an output from the first fuel injector, and determine a state of the first electrical relay by comparing the output from the first fuel injector to a predetermined parameter.
