I had the same issue as you every body else. So I replaced my pump because it wasn't working. So I rerplaced it with a new one. Me and my mechanic started to look at the pump and noticed there was just a bad connection on the inside. I sent it to an Electric shop where they repair electric motors and they saddered the connections tested and works great. So if any of you have the same issue pop of the cap where the three screws connect for the electrical plug side of the pump. you may not have to spend $700 for a new pump. Since I did by a new one I have a used one for sale if any body is interested.
