I just bought a new house that was winterized and vacant for about 6 months. It has a deep well with a jet pump. When I turn the pump on, the tank does not fill up but water does come out of the taps. The pressure doesn't go over about 40 kpa and the pump never shuts off. I've been keeping the pump turned off unless I actually need water.
I had a plumber look at it and he said it was probably something obstructing the jet in the well, but he won't be able to come back to work on it for several days. Is his diagnosis accurate? Is this something I could do myself? I couldn't find any instructions for pulling a jet out of a well online.

Sounds like there is too much air in the tank. Or he bladder is actually broken in the tank.
Depending on where the valve stem is you can check by removing the valve core and seeing if water come out of where the air should be. Meaning you have to replace the tank. Or add air to the tank with a nearby faucet open and if possible close all valves leading to the house in order to shorten up and isolate the tank. If air comes out of the open tap. Bad tank. Also the tank could be flat. In which case add air and start draining the tank. Don't add too much air this could rupture the bladder
If you get the tank drained you want to set the air at around 2-3 psi lower than your low pressure switch setting
