Water pump question

I just started having issues with my water pump.
It started last time I went camping without a water hookup I used the pump everything worked fine except the water would shoot out the city water intake.i was told to get a cap for it or to get a new city water check valve.Well after capping it,I tried to use the pump with the water tank ,it goes on but doesn't pump any water.
Could this still be a valve problem ,or does it sound like a pump issue ,there is no debris in pump

Does the water pump shut off automatically (after pressurized )? Is there a leak somewhere?

When you took the cap off did it start shooting water out the city water hookup again? It seems like capping the outlet would be the same as a valve to me. Haven't tried it though.

There is often a check valve in the pump to allow pressure built up not to leak back into the tank. There also may be a check valve between the city water hook up and water system to prevent back flow into the campground system if pressure dropped. One or the other of those check valves is leaking. The pump check valve maybe replaceable, you didn't mention the make and model. The check valve in the city water line also might be easy to replace, it would either be inline or a part of the city water hook up.
