hello mr.scotty i my mercedes e320 2003 was flooded and i changed the transmission fluid and the motor oil and i tried to turn it on but it cranks but does not start so i had a new crank shaft sensor, still does not start, i cranked it for a long time then alot of smoke started to come out, then it does not crank any more, so what have i broke, and what might be the problem is ?

if flood got near dash height, junk it. Electronics on those are everywhere and not worth fixing when they are all flooded out. 'also, start with an engine compression test, and if it's low, junk it faster

but what have i burned in the car ?
