Recall 04V090000: Intake Manifold Fire Hazard

DEFECT: 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 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 manufacturer has reported that owner notification is expected to begin during the second quarter of 2004. Owners may contact Buick at 1-866-608-8080; Oldsmobile at 1-800-630-6537; or Pontiac at 1-800-620-7668.
