I put it all back together and it still made the same noise and did not pump at all.
The power source is a little jacked up as well as the pump runs for a while then shuts off. This is being addressed today but what do you think is wrong with the motor?
Thanks!

I am new to the site but deal with pumps daily with my job. Make sure that all your valves are open so that water can pump through. Under no circumstances should a pump be run without liquid...unless designed for it. The reason for the smoke was most likely the seal kit creating friction. does it sound like you are trying to pump gravel? or maybe marbles? if so you may not have enough back pressure on the suction side of the pump. this creates air in the eye of the impeller which contain enough heat to create steam, when it creates steam is is a small explosion inside the pump thus the gravel sounds. when that happens you can most definitely ruin your impeller and volute casing...a pitting will happen.
Also make sure the entire inside of the pump is filled with water...if air gets inside there, then it creates a buffer to where water will not be able to pass.
