ABSTRACT:
A fuel control system for an engine is disclosed. The fuel control system may have a source of pressurized fuel and at least one injector configured to receive and inject the pressurized fuel. The fuel system may also have a sensor configured to generate a signal indicative of an actual fuel pressure at the at least one injector, and a controller in communication with the sensor. The controller may be configured to determine a desired fuel pressure at the at least one injector, and compare the signal to the desired fuel pressure. The controller may also be configured to initiate a leak detection sequence in response to the comparison.
