If the battery was disconnected, as it should have been for the pump replacement, then the ECM needs to go through what's called a "re-learn", where it re-learns the driving characteristics of the owner. With some vehicles, this can actually take a day or two, and until it settles in, the car will act strange. I would recommend driving it for another day or so to see if the problem goes away. If it doesn't correct itself after a day or two, take it back and tell them you want it fixed.
Take care,
