Abstract
A method of monitoring operation of a fuel system includes urging a fuel flow from a fuel source toward a pressure regulating valve via a fuel pump. A pressure of the fuel flow is detected at the pressure regulating valve, and a pump speed required to produce a selected pressure at the pressure regulating valve is detected. The pump speed is compared to a range of acceptable pump speeds, and an operational status of the fuel pump is determined based on a result of the comparison.
