your problem is more than likely one of a few problems
there are two hoses on your transfer case one sucks in one blows out if one gets cloged it will go out completly so have it checked its starting.
or check the oil in the transfer case

I had the same problem with my 96 Aurora. I guarantee it's the fuel pressure regulator. Had mine replaced by GM dealer started like a new car

Here is what you do, but only when the SECURITY light flashes - if it is always ON or OFF it's no use.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes ( SECURITY light will flash for 10 minutes and then stay on SOLID)
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the ignition OFF.

Start the car normally.
It has relearnt the keycode and you're good to go.
NOTICE - it takes 30 minutes to relearn, that's THREE cycles of ON - 10 minutes - OFF.

Good luck.
