Battery is going dead every night with a 1.5 - 3 amp draw on my battery. I have a 1992 buick regal gs 3.8L

You need to eliminate some possibilities.
While reading your amp draw, you can start by pulling fuses. Make sure you don't have a glove box, trunk, or hood light on.
I have had an alternator issue that had a constant draw. I removed the large wire on the alternator and the draw went away. You can do this for your starter also.
Pulling relays may also help, just go one at a time.

I have a 99 Buick Regal GS, engine will start and run for few seconds then it will die.

I had a similar problem....my 98 regal GS did the same. There is a two stage fuel pump resistor located in the right inner finder. It was corroded and open. The fix requires relocating new resister on firewall. Fix was $165.00 + tax to my mechanic and runs like new now. Hard to diagnose problem per mechanic.

I have a 1999 buick regal ls dying.

I have a 99 Buick Regal and it too dies out, but only when I use my turn signals. Sometimes, when trying to start the car...the dash lights would flicker and you can hear some sort of electrical ticking sound. As of today, my car will not start (5/24/09) it hadn't turned over since yesterday. After a process of elimination and searching the net, I think I need a new ignition switch. You may need one as well.

Check the idle air control as it is operating when you start the car and after the car warms up it is out of the system.
