I need help!!!
 

I was driving on the highway when my car died on me! I thought it was the battery but everything turns on still the engine just won’t start! Any ideas?!
2009 Hyundai Accent

Well, that isn't a lot of information to go on.
We are not there so can not see it
Nor can we do anything to test it

So assuming that the engine cranks but doesn't start??

Have you done any testing to see what is wrong?
Check for spark?
Check for fuel ... fuel pump prime, fuel pressure at rail, injector pulse
Is the check engine light on?
