Upon accelerating onto the highway, after reaching highway speed, vehicle stalls and would not start. Flooding engine, gasoline coming out of exhaust, engine would not restart. After research and replacing leaking lower intake manifold, this was not my problem there was no leak. After more research I replaced more sensors and eventually cylinder gaskets and lower intake gasket again. Still engine would not start. After 2 years of car sitting I unplugged maf sensor and then it started finally. Faulty maf sensor but no way to find out unless it is unplugged because sensor did not give off any pertaining fault code pointing to the problem specifically.

Fuel system, gasoline:delivery recall for 1999 pontiac bonneville recall announced: february 24 2004 the federal safety agency reference: #04v090000 number affected: 910,873 summary: on certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire. Consequence: the backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire. Fix: dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. Owners should contact buick at 1‑866‑608‑8080, oldsmobile at 1‑800‑630‑6537, or pontiac at 1‑800‑620‑7668. For detailed information & supporting documents, see the official the federal safety agency page concerning recall #04v090000.

My 1999 pontiac bonneville exploded when the key was turned in the ignition & fire shot out from under the hood. When the key was turned off, the fire stopped. I had the car towed to a private mechanic who replaced the a fuel injecter & upper intake plenum (which was in pieces from the explosion). My bill was $430.63. In june 2004, I received a recall letter from gm corporation saying there was a safety issue with fuel pressure regulator diaphragms leaking. The letter described the following: "a leak can allow fuel to enter the intake manifold through a vacuum line. In low battery conditions, if the engine does not start when cranked, the fuel from the leaking regulator and a spark can cause a back fire. The back fire can rupture the intake manifold, causing a loud bang. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak. If there is an ignition source, a fire can result." this letter described exactly what had happened . The lights had been left on in my pontiac which caused a dead battery. A battery charger was connected to the vehicle when the explosion happened. When we tried to start the car again, the fire started again where the intake manifold was located. I made a request for reimbursement to gm. My file # is 1-260698900. I was asked to take my car to a dealer in salisbury for an inspection. When I took the car in on sept. 29, 2004, the fuel pressure regulator was replaced. According to the recall letter, an inspection will be made and, if necessary, the regulator will be replaced. So the recall condition was fixed by this replacement. Gm refuses to reimburse me for my repair saying I have no proof the recall condition caused the explosion. I was given no recourse to dispute their decision. The condition described in the safety recall letter was exactly what happened to my vehicle in february. Help.

I have a 1999 pontiac bonneville. The car would not start and I had it towed to dobbs. Dobbs investigated and found that the upper plenum had warped. Thereby causing the starter to fail and antifreeze to get into the engine. Pontiac knew about this problem and corrected it on the year 2000 model. However, they did not do a recall and left us poor saps to have to pay for the repairs ourselves. Since my car is out of warranty, they have said that it is my own problem. I am out of pocket $1,046.96 plus $40 towing fee for a problem they knew about and didn't recall. I wish to be reimbursed.
