Well problems My options???

To pay a driller to get it out will probably be expensive "if" it can be done.

You could build a tri-pod with a winch, then make a reverse driver then pound on the top of the pump, drive down then up.

A reverse driver is a piece of vertical sloted pipe smaller than the well casing. The slot lets the driver slip around the existing pressure pipe and is lowered by the winch. Sharpen the edges of the driver so it removes side wall rust as it goes down, then bump the pump with the driver until it comes loose.

If the pump was set too far off the bottom then you will need to add a joint of pipe with a casing stop, (two bars that clamp around the pressure pipe that stops the pump from falling to the bottom).

With pressure pipe and wiring your probably looking at 600lbs or so at 100ft. I bet the Pipe Joints will have to be cut instead of unscrewed when you pull it.

I also have a 4" well. 6" is standard around here. Those 3 7/8" pumps will work if the bore is perfectly straight. Mine wasn't. Turns out Grundfos manufactures a smaller diameter pump.

I haven't found anybody else that does. When you do finally get it out, strong recommendation to never relive your problem by putting a smaller d. Grundfos down there. Pressure, gpm, connections, everything else is the same, just smaller d., around 3" IIRC. You'll probably have to call them to find a distributor.
