2000 Buick Lesabre & 2000 Buick Park Avenue + 3 more recall: fuel system
⚠️ What's 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.
💥 The 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.
🔧 The 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.
