Abstract
A method and system for determining degradation of fuel pump performance in a locomotive having an internal combustion engine is provided. The method allows for monitoring a signal indicative of a fuel value delivered by the fuel pump and for adjusting the value of the monitored signal for deviations from an estimated nominal fuel value due to external variables to generate an adjusted fuel value. The method further allows for comparing the value of the adjusted fuel value against the nominal fuel value to determine the performance of the pump.
