If you up-graded the pump, you may have exceeded the amp capacity of the existing wiring. I know some pumps say they will not work right on wires smaller than 12 gauge, etc. Check the pump requirements as to the wire size. This would also explain the low voltage at the pump if the supply wires are too small for the new pump.
I replaced the OEM pump with exactly the same model because I needed to limit potential problems with a different pump. Now I'm glad I did this because I've got enough on my hands with the current problem
