The rack and pinion focusing mechanism will not go in and out. how do i fix this?

There is a simple gear inside -- take the bottom plate off the focuser and see if they are engaged or broken.

If a gear is broken you will need to buy a new focuser.

Not worth repairing-- a new focuser for your telescope would cost as much or more than the telescope-- unless you can find a discarded telescope of the same model..... for parts.
