Fuel system, gasoline: delivery
- What is wrong
- 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.
- Risk
- 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.
- Remedy
- 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.

What 1998 Buick Lesabre owners say
Most recent owner complaints, unedited.
Observed a strong gasoline odor after driving the car. The cause of the odor was a leak in the nylon fuel pressure line feeding the rear fuel rail on the engine. The leak in the line was caused by the engine shroud. The engine has a removable plastic shroud, and the edge of the shroud was rubbing on the fuel line and eventually cut through the line and created a pinhole leak.
The fuel gauge on my 1998 buick lesabre automobile is faulty. The gauge gives inaccurate and random fuel level readings while driving.

I am currently the owner of a 1998 buick lesabre with approximately 24,600 miles. I recently had to have the fuel pressure regulator replaced on the vehicle after the car backfired and the service engine light appeared on the vehicle. The engine was chugging and the exhaust smelled like gasoline and burning plastic. At the service shop where I had my car repaired, the mechanic informed me that it was good I brought the car in so soon because this sort of problem if not fixed could have resulted in a possible fire. I contacted buick customer service in regards to the problem and was informed that my specific vehicle was not involved in any recalls and that the fuel regulator in my vehicle was not a part of any buick recalls. When asked if I could receive some documentation that my specific vehicle was not a part of any recalls, I was told that they could not provide me with that paperwork and that anyone else could talk to with buick would tell me the same thing in regards to my vehicle.
The fuel supply line rusted get in to the plastic fiting and gasoline was leaking at the gas tank.
