1997 5.7L V8 Camaro Won't Start

My car is a 1997 Chevrolet Camaro 30th anniversary with the LT1 engine. Was running excellent. Believe the car has a few extra modifications too it but not too sure. I have gas and the car was running then all of a sudden it sht off. Power is still coming on and the engine is clicking and trying to start but it's just not starting. I bought the car a year ago with originally 59k miles and it now has 68k miles. A tune was done just before i bought the car.Need help. If you have any ideas please let me know. My aim is ilcamaroboy and my e-mail is [email protected] thank you
P.S. I live in the aurora area.

for one we need more details like how manny miles and have you ever did a tune up on it and stuff like that. And where at in IL are u located?
