New Waterpump won't work

[rohrmann]

Something plugging the line from the tank or a pinched line from tank to pump. Wonder if you can access the line from the tank and blow air back toward the tank to prove it clear? You might even have a loose fitting allowing a bit of air, which would not let pump suck water to the pump. Another thought, is the tank fill valve in the proper position? If in the fill position, don't think the pump will move water.
