ABSTRACT:
A fuel system diagnostic module comprises a pressure module and a fault diagnostic module. The pressure module determines first and second pressures of a fuel rail of a fuel system at first and second times, respectively. The second time is after shutdown of an engine. The fault diagnostic module selectively diagnoses a fault in the fuel system based upon a comparison of a predetermined period with a period between the engine shutdown and the second time.
