Fault isolation in electronic returnless fuel system
Abstract:
A method for detecting and isolating an actual fault in a fuel delivery system having a fuel pump and a fuel pump motor, includes monitoring fuel pressure, pump current, and pump voltage. Each of a plurality of fault triggers are designated as one of flagged and un-flagged based on at least one of the fuel pressure, the pump current and the pump voltage. The actual fault in the fuel delivery system is isolated from a plurality of possible faults when a condition respective to one of the possible faults is satisfied based on at least one of the plurality of fault triggers designated as flagged and un-flagged.
