Since all your lines appear to be clear, and the impeller "appears" to be intact, it should be checked for slippage. Sometimes the rubber part breaks away from the center collar, or somehow the shaft key gets dis-lodged. Try holding the impeller while turning the shaft, to see if anything slips. If that's OK try checking the shaft itself for any slippage.
Concerning the thermostat, The PO probably removed it as a temporary fix for overheating, but a faulty thermostat would not cause a pee hole flow stoppage.

P.S. Since the lower end is already off, the impeller should be changed regardless.
