I have a 2004 Sierra Sport toy hauler. To use my fuel station, I turn on the inside switch first (the light comes on- in the switch). Then go outside, position the fuel handle, then pull out on the outside switch and then the pump turns on. I think the two switches work's to cut down on gas theft. Sound like a bad pump or a bad switch. let us know what you find.
