With last use being winterizing, it is likely the valve near pump is still turned to suck from antifreeze jug rather than fresh tank. If so, pump will just suck air through open line.

This is probably issue #1. You should have a valve right before the pump. Turned one way it pulls from your tank, turned the other it pulls from a short section of hose meant to feed into your antifreeze jug.
Issue #2 is probably a water heater bypass valve, because when you pump in antifreeze, you usually don't do it in the water heater.
