Hi,
If you presently have fuel and spark, the engine should run. By chance, does the engine fire and then stall when you try starting it?
Also, here is a link that explains how to retrieve diagnostic trouble codes on this vehicle. You don't need a scan tool. All you need is either a short jumper wire or even a paper clip.
Follow the directions in this link and let me know what you find:

Next, I don't know if the vehicle has one, but is there a security light or anti-theft light staying on or flashing?
Let me know.
Joe
