Fuel system, gasoline:delivery recall for 1999 Pontiac Bonneville recall announced: February 24 2004 NHTSA 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.

There has been a problem with a gas leakage. The fuel supply line fitting at the fuel injector rail was the problem. O-rings were replaced, things seemed fine - no gas smell or leakage. This lasted for appx. 24 hours. I drove about 7 miles to and from work three times, a total of 21 miles, stopped at a library, came out, smelled gas, was driving the car home - one mile - was going to park it and get someone to look at it. I stopped at the mailboxes and heard a slight poof sound under the hood.when I looked up I saw smoke bellowing out from under the hood. I grabbed my purse and jumped out. From a distance I saw 2" balls of fire dropping from the engine to the street, called the fire department and watched my car go up in flames while waiting for them to show up - all because of one small plastic piece under the hood. Also, I would highly recommend everyone to carry full insurance coverage - a lesson hard-learned.

G.M recall # 040V09000 was performed on my 1999 Pontiac Bonneville on July 2004. Fuel pressure regulator was replaced, the part has failed again and had to be replaced again. I contacted Pontiac and asked to be reimbursed for the cost of the part. Pontiac has informed me they will not cover the cost of the part as the car is out of warranty. The car was not under warranty when the part was recalled and replaced in 2004. Is GM only required to replace the part one time?

The contact owns a 1999 Pontiac Bonneville. In 2003, while driving 15 mph, the contact noticed a huge cloud of white smoke at the rear of the vehicle. The dealer stated that the intake manifold had blown the gasket. The intake manifold gasket was replaced as well as the intake manifold itself. In 2005, the fuel pressure regulator switch blew out and was repaired under recall; however, the failure recurred in 2007. The vehicle was taken to an independent mechanic and the contact was informed that this would cause the engine to blow due to leakage of fuel into the engine. Also, the rear window defroster switch would not shut off. He had to remove the fuse to prevent it from draining the battery. The failure mileage was 63,000 and current mileage was 104,000.

Vehicle has performed perfectly since purchase. My wife experienced hesitation upon entering a busy intersection and almost caused an accident. Upon inspection, the intake manifold (plastic) is warped causing a large gap at the interface to the throttle body allowing antifreeze to enter the engine and also causing an intake air leak which is degrading the air/fuel ratio.

The fuel sensor was faulty, which caused the vehicle to leak gas.
