It is stuck in the high speed mode.

If it is a new pump, send it back.

There is a pressure sensing device inside if you wanted to tear into it. It just might be jammed up with some debris/trash.

Did you max out the cyl to see if the relief came on?

If you were splitting pine or some light weight wood, it might not have had a chance to go to low speed, high pressure.

the pump is used I put a guage in line can only get about 700 at wide open (3200rpms)

You still did not say if you held the lever at the end of stroke to make the valve go into relief, and develop max pressure.

Relief pressure is usually around 2300 psi.

the cylinder was maxed out right up to a chunk of wood engine was laboring maybe 3200 rpms an the guage was about 700 psi.

This is a HF two stage pump, but may be similar to yours.
