So you have spark and fuel. How about compression?

By "car is getting gas" please elaborate... What is your fuel pressure at the schrader valve? If the car starts on starting fluid than its probably not getting gas!

I'd rule out VATS, but you haven't said anything about the security light (VATS disables the injectors and the starter enable relay).

Without knowing fuel pressure its hard to say, but if your not going to check it, then you should investigate the fuel pump relay. Also note if you hear the fuel pump prime from the back when the key is turned but not started. TO make it prime again you have to wait 10 or 15 seconds with the key out.

Bad gas? Old gas? Do you have gas in it?

If it sat for forever you might have seized a piston in the cylinder - and broke it when you started the car, doubtful, but if you check fuel pressure and its good, then the next logical step is compression - as you've checked for spark already.

Yes it is getting enough air.
----------
It has fresh gas all the relays under the hood checked good I do not know about the fuel pressure I know the valve where you check the fuel pressure is pushing out gas where you push it in.

As stated above, you need to check the fuel pressure with a gauge. Thats where I would start.
