A machine includes a compression ignition engine fueled from common rail fuel injectors that predominately inject natural gas fuel that is compression ignited with a small pilot injection of liquid diesel fuel. When an engine shutdown command is communicated to an electronic controller, the supply of gaseous fuel to the gas rail is stopped and the gaseous fuel common rail is depressurized by continuing to run the engine and inject gaseous and liquid fuels while commanding a liquid pressure greater than the gas pressure. After the gas rail pressure has achieved an acceptable shutdown pressure, the engine is stopped. The gas rail pressure is then reduced to atmospheric pressure followed by the liquid fuel common rail being reduced to atmosphere pressure after stopping the engine.
