When it is on it won't start. When it's off it fires right up.
I never knew it had the worthless theft carp on it. How do I fix that?
Yep, the legendary Passlock system.
I had a '99 Malibu as well. I really loved that car... and this problem was my biggest complaint about that vehicle. It would hit me every so often. Usually what would happen is everything is fine.. I go to start the car, and it would *almost* fire right up, but something amiss would trigger that Passlock system, it would cut fuel/spark and the theft light would flash for ten minutes.
After that ten minutes, generally I would be able to start the car. There were a couple times I couldn't and it would re-activate.
Usually if I had a new key cut it wouldn't happen again for 6-9 months. Eventually I took some spray lubricant of some sort and shot it right into the ignition key hole. I don't remember having a problem with it after that, honestly.
But the real fix is a new key cylinder and ignition key itself, IMHO.
