Sounds like the anti-theft system is cutting off the fuel. GM anti-theft systems are very effective at keeping owners out of their cars.
Try this. Turn the ignition switch on, try to start the engine for just a second, relax the switch right away but leave it on for at least ten minutes until the "security" light goes off. Turn the ignition switch off, then right back to on for another ten minutes, Don't crank the engine. Do that again a third time for another ten minutes, then without turning it off first, try to start the engine.
I hope I have that right. I read this procedure a lot from other people having the same problem. Another common problem is broken wires in the steering column for the Pass Lock sensor.
