104V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
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 & remedy
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.
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.
