* I CHECKED ALL THE FUSES THEY ARE ALL GOOD
* I TRIED SPRAY IN STARTING FLUID BUT WONT START

There is only one thing, does it have compression?
3 things needed are fuel, spark and compression.

Ok, you have the dual overhead cam motor. You need to check the belt. You are right at the time for replacing the belt. If it breaks, it will bend valves and complicate things.

OK SO WAT ELSE CAN IT BE?

When the engine cranks, does it sound odd? If the belt broke, you most likely have bent some valves.

No it cranks up like a regular car. It has new alt new battery and starter. The car was working fine and while I was drivin it just turnd off.

Have you checked the following: Spark (should be blue snapping spark)
Fuel and fuel pressure (should be within manufacturer's specs and
be getting a good pulsing power to each
Engine compression Should be within the manufacturer's spec.
