    Check to see if the injectors are pulsating. If not, sounds like theft deterrent prob.

    Have you tried starting it, and giving it constant gas (just a little)? If it still runs, the the problem is definately in the fuel pump/carb or tbi area. Being a '91 I am hesitant to say that its the fuel pump switch, which is electronic on newer cars. If the car does not run while you give it gas, then I have no idea man. It's one of those things you kinda gotta be there for to pick up signs and such.

    i have the same problem. did you figure it out? cause really i started mine with a screwdriver at the selunoid and started fine a few times and ran fine. next i put a switch in and tried to start it to bypass the ignition, i am starting to think it is that stupid security detterent theft thing, now also how can i bypass that or simpley just remove this stupid feature on the buick? I am really at a loss here.
