Ok
I got a 1997 Hyundai Tiburon.
It over heated and hasn't ran ever since. It turns over fine but won't fire .... I need help with this

 

Overheating can sometimes cause the head gasket to fail which then allows for a number of possible problems
One is coolant into motor oil or the other way around
Another is loss of compression which would not be helpful in starting an engine
Or it could be a bad crank or cam sensors
Even something else that I haven't heard about

It should be back to basics and start by checking to see if you have spark, fuel
And let that lead you to where look

Good luck to you
