if the converter isnot seated correctly you will break the pump on start up

An incorrectly installed converter is the likely problem, and it true, it likely also broke the pump rotor.

See my post #8.

Do you remember if there was a gap between the converter and the flexplate?
When there is, you can turn the converter very easily before the first bolt is installed.
