I checked this by unhooking the
hose from the impeller to the thermostate housing and its not getting any
water.

So, with the outlet hose from the raw water pump disconnected, and the pump
turning, no water comes out?

And you know there isn't a blockage between the pump and the water intake?

Then I would say that there is a large air leak between the pump and the
water intake, or a serious block right at the pump oulet.

Another possibilty comes to mind: Is it possible that while investigating
the problem you reassembled the water pump wrong? Could you have swapped
intake and outtake on the pump?

I would suggest getting a length of hose that will fit the pump intake and
running an experiment. Disconnect the existing hose, hook up your
experimental hose. Drop the free end into a bucket of water, and see if it
will pump that. Also, try disconnecting the outlet hose right at the pump.
