No water pressure on well jet pump
Hi, I have a well that is used for watering the lawn n outside. A couple of days ago, the pump would run non stop. It had ran all day and the pressure wouldn't increase at all. I shut down the pump and started reading on how to troubleshoot the issue. I emptied the reserve water and checked the pressure tank. It was at 0psi. I got it back to about 40psi, primed and ran the system again. But when i ran the water it instantly dropped and the pump just wouldn't build back any pressure. Also the hose started to spit air and finally no water. I couldn't find any leaks from what i could check.
There are the details to my system
2 line jet pump (the lines goes directly into the ground
theres a tap for the city water for easier priming
since the lines go into the ground/dirt, i can't check the venturi or the filter underneath, or rather i don't know how to. it seems like the well was put in then the house was built on top (pump is the the crawl space). Do you guys have any ideas on what could be wrong or how to further troubleshoot the problem? I also don't understand how can the lines just go into the ground and not a bigger hole.
Thanks

Ok i have some updates, I finally found the well head after digging alot of the yard.
The jet pump is a Gould CJ5 jet pump at ~29 yrs old
The pressure tank is a well-x also ~29 yrs old
Its a 2 line deep well that goes into a 2" packer.
My pressure tank doesn't seem to holding pressure. I'm not sure if that is normal since my pump is currently off. It seems to be losing pressure slowly. Also theres a new symptom, before when i turn on the pump the pressure would fluctuate a lot but it would go up slowly, now after primping it theres no fluctuating and it goes down slowly.

"it seems like the well was put in then the house was built on top"
I once saw a well in a crawl space that had a piece of the floorboard cut out above it and replaced so that the pipes could be pulled up and out. Next time you are in the crawlspace try looking up and see if there is something like that.
If the pipes are made from poly, they might bend as they come out. If PVC, they can be cut, but if they are metal, then you may need a sawzall for the floorboards. Unless someone here has a better idea.

Since your well is buried I would try a new pump. Hopefully you can borrow one just to test. I think the pump is a 50/50% shot of being your problem. If that does not work I think the well needs to be pulled to check the venturi and inlet screen. I doubt your house was built on top of the well but some wells are buried to protect against freezing. If they did not mark the location... good luck.
The pressure tank will help moderate the pump cycling on and off but it has nothing to do with the pump pumping water or it's ability to generate pressure. So, for now you can leave it out of the equation. It probably still needs replacing but replacing it will not make the pump work.

yes after lots of digging and tracing the lines, i found the well about 6 ft from the house 3 ft under. I originally was going to try to pull the venturi and foot valve and check them, but i found out i have a 2" packer style well and figured that the "leathers?" were going to hard to pull out. So i'm trying to see if the problem is w/ the pump now. but since it is so old its hard to disconnect all the piping and lines from it as everything seems like its rusted on or just wont move. Any tips on removing poly pipes thats been stuck on the connector?

As for removing the poly lines, take a heat gun and blow around the line at the fitting a little bit to heat up?soften the line temporarally, not a lot of heat but a little usually lets the lines pull off fairly easily.
