Answer
Hi Rudy Camacho,

You are not getting fuel.  Try loosening the gas cap and see if that helps.  Today's cars have no vents on the tank that don't have something to regulate the amount of ventilation.  One of these systems may have failed.  Loosening the cap stops a vapor lock.  

If that doesn't do it, suspect a fuel pump regulator.  Get a fuel pressure tester and see what delivery you have.  Should be about 50 psi.  Too low means weak pump or too much bypass.  Bypass is regulated by the regulator.  

Then suspect EGR issues.

If these don't do it, write back and we can try more things.
