ABSTRACT:
A fuel injector diagnostic system includes a fuel pump control module, a pressure sensor, and a diagnostic module. The fuel pump control module disables delivery of fuel to a fuel rail of an engine. The pressure sensor measures a first pressure of the fuel rail before an injection event and a second pressure of the fuel rail after the injection event on at least one of a plurality of injectors when the engine is running. The diagnostic module diagnoses a fault in the at least one of the injectors based on the first pressure and the second pressure.
