2000 Pontiac Bonneville Starting Problems
On February 16, 2004, General Motors informed the National Highway Traffic Safety Administration that it would be recalling certain 2000 Bonneville Pontiacs for an issue causing drivers to experience backfires if the engine was not starting when cranked. Owners of this model experiencing starting problems should contact NHTSA to determine whether their vehicles were affected by this recall.
Cause
2000 Bonnevilles equipped with 3800 V6 L36 engines and certain Delphi Fuel pressure regulators may experience a high level of fuel leaks that can let fuel into the intake manifold. The manufacturer reports that if the engine doesnt start when cranked, the car may backfire from the regulator fuel leak.
Consequence
If the Bonneville backfires, the intake manifold may rupture. A rupture could cause the fuel line and fuel injector to displace, leading to a fuel lead or fire that could cause injury or property damage.
Solution
Take affected vehicles to authorized dealers to have a new fuel pressure regulator installed. Call NHTSA or the manufacturer with the VIN number of the vehicle to verify that it was recalled, if necessary, or to find out where to take the car for free repair.
