hello tamwa, did you get your problem resolved? If you did could you post on here what you did to get it going again. I am having the same kind of problems with my '96 bonneville ssei supercharger.

You need to verify your fuel pressure. You can get loaner pressure gauges at certain auto parts stores in this state of Ohio. Don't know where you live. The pressure should be tested with the engine off and the key on. The pump will run a couple seconds and then shut off. The pressure should hold unless there's a bleed down from a leak or the fuel pump. Then the pressure should be checked with the engine running at idle, and then the pressure noted when the engine is accelerated causing the vacuum to reduce which lets the fuel pressure regulator up the pressure.
Second choice would be the MAF sensor may need cleaning.

ive heard a lot of horror stories about it being a feul pressure regulator and if not fixed can be very bad for both the car and you .it can pool gas in the intake and explode the intake off.there about 60 bucks

also there is a ground under the kick plate on the driver side that gets corroded and can cause all kinds of fits#233 of 233 Re: 2000 pontiac bonneville fuel pressure [yamiracer] by scscars

I had this problem late last year. It is related to the MAF sensor. Worn motormounts created stresses that "tugged" on the MAF sensor and caused it to malfunction. Replacement of one of the motormounts helped, along with a MAF sensor cleaning. I still need to replace the second motormount and probably should replace the MAF sensor as well, even though it is only about three years old. So far, I've spent about $350 on this problem. I have a 2002 Bonneville with a non-supercharged 3.8 Liter V6. Hope this helps.
