Fav not opening

[Philip Martin]

I finally got the gauge mounted and the wiring ran.In the first step of priming the pump and clearing the 6mm line out to the Fav.Did the jumper from FAV to SYS and sure enough water shot out.Connected the hose to the Fav and cut the switch back on.Nothing came out of the FAV.I unscrewed the fitting into the FAV, and cut the switch back on.Water sprayed out of the fitting, so water is making it to the Valve, its just not opening.When the line is removed from the FAV when the switch is on, the gauge is showing flow and water is shooting out.When I attach it to the Fav its not flowing and the water level light is burning, but it doesn't burn when the water supply from the pump is not connected to the FAV.I also filled the tank up a few times and the light for the water level would not go out.
