The Navigators have something called a Fuel pump driver module that is known to fail and this can cause the fuel pump not to run. This fuel pump driver module is located above the spare tire on the drivers side of the frame. The connectors can get corrosion in them causing a bad connection and this can allow the fuel pump not to run but most of the time the modules just need to be replaced.
