Hooked up water in winter and can't get water pump to pump water

i brought out my 2012 FC for New Years. It was winterized.



Hooked up everything I thought but the water pump isn't pumping water. Barely any water comes out when I'm off grid and using fesh water tank. I hear the pump running but am not getting desired results.



I'm new to all of this so what could it be? I relight ended the valves to the water pump with no luck.
