My Topeak JoBlow pump handle shoots up when I connect it. It feels like air is getting back into the pump and it barely pumps up my tire.
What’s wrong with it?

Sound like the valve on the tube is sticking open at the end of your pump compression stroke. It’s happened to me. I just keep pumping and ignore it. You could take the valve core out and put a little grease on it but it’s hardly worth the bother.
