2002 hyundia sonata will not turn over

Start by cleaning all the connections, both at the battery and the starter. Be sure you have a good ground too.

What does "turn over" mean?

The engine cranking to start.Starter turns the flywheel that in turn will rotate the crankshaft.

If the battery is weak or otherwise not getting enough power to the starter it may engage but not turn.

That was my assumption, too. However the op said that it is getting "fuel spark". I don't know what "fuel spark" is. Usually need the engine rotating to get spark plug spark. So, possible hydro-lock.

I think possibly English is a second language and limited punctuation.

My English is ok and punctuation is too. The problems not an English or grammar issue. The problem is that I have taken all the components off the engine as instructed to check the timing belt. I found that dirt dobbers had built a huge nest and when the car was started it appears the belt slipped from the crankshaft pully due to dirt clogging the gears. I turned the cams back to specs but the crankshaft will only move about a 1/3 rotation. My question is; does this indicate lower engine failure? Maybe a bent rod or something? Please look through the bad grammar and provide assistance. It's hard typing on this iPhone Thanks Larry

This is an interference engine.

May not be a bent piston rod, more likely piston hitting a valve. Piston possibly damaged. Valve(s) damaged. Possible head damaged.

Thanks Paul so does that mean go ahead and replace the short block? The crank only rotates a third rotation

I cannot answer that. You may want to investigate and determine what is wrong with the engine or just replace the entire engine without knowing what went wrong with the old one. A short block will not fix destroyed head and cams.
