If you removed the hose from the pump and no air comes out when you try to pump it, it sounds like the check valve is stuck. I don't know how you would unstick it.
I have an older version of that pump, and I checked it when I got home, I can make the same thing happen when the pressure gauge is turned backwards. So try reversing the pressure gauge.
