Help please!

My tank just finished cycling. Was going to do a water change and get my first inhabitants tomorrow. But my return pump just made a weird noise and a puff of smoke came out. Also a burnt motor smell. The pump was still working but I unplugged it. What do I do?? Do I need to do a 100% WC? It's a IM fusion. 10 gal tank

So a 100% water change in a 10 gallon should be a nice precautionary move. I would pull the pump and take it apart, see what happened on the inside. If it is a cheap pump than might just be worth replacing rather than trying to fix it.

Thanks.. just got the pump out and tested in bowl of water and it is surging so pump is bad I'm guessing.. it was the one that came with the tank. I'll go buy a new one tomorrow I guess and do water change also. Should I still be good to go to put fish and whatever in the tank once I do a water change??

So most likely the bacterial growth in the rocks and substrate shouldn't be affected by the pump burning out. I would get a new pump working then do a 100% water change. Would check parameters 24 hours later but wouldn't expect another cycle.
