When you changed the impeller what did the inside of the pump look like? Was there any scoring on the cover plate or the back wall of the pump? I had a similar problem and the issue was that I was getting water just not enough water. And the cause was the scoring on the inside of the pump did not allow enough vacuum pressure as there was "Blow by" due to the scoring in the pump.
