OK, so I'm pretty sure now its the pump. I manually energized the pump relay and the pump won't budge. You can hear it try to but no go. I took the pump top off and tried turning the blade manually but its SEIZED! Took apart further by taking off all the bladed to find out that everything underneath is rusty! Took apart even further and as you can see in the pictures, everything is rusty! So much for a "sealed motor" design! I have not put it back in yet so thats why I say "I'm pretty sure its the pump".
