Nhtsa #: 04v090000 - I own a 1998 Buick Lesabre 3. 8l. On 9/27/02 I had a hard starting and stalling problem, taken for service at gm dealer and fuel regulator was replaced. In August 2004 was notified of the recall and took vehicle back to gm dealer to assure the recalled part was not in the car. The dealer told us the car does run a little rough (noted on work order) but the correct regulator was in the vehicle don't worry about it. On October 10,2004 we started having trouble starting the car. On October 11 we made an appointment to take the vehicle in for service on October 18, 2004 to an independent service shop. On Thursday October 14, 2004 and Friday October 15, 2004 the car stalled once each day when moving in traffic at a very slow speed. On Sunday October 17, 2004 while my wife was following me to drop the car off at the repair shop, the car again stalled. She put the car in neutral and restarted the car. When the car started it jumped forward and she struck the back of my truck. The repair shop found the fuel regulator to be leaking fuel into the vacuum hose and into the exhaust manifold. This was the part that according to the gm dealer was not part of the recall on August 11, 2004. The end result is there is $3000. 00 damage to the Lesabre, non to by truck. My back is slightly sore but of greater concern is the seat belt did not lock on the Buick and my wife struck her chest on the steering wheel hard enough to have bruising in the outline of part of the steering wheel on her chest. In summary Im concerned about the 1. ) fuel regulator, 2. ) the car jumping and 3. ) the seat belt not locking.

20 Fuel Delivery problem

Above mentioned vehicle came into my auto repair shop with a very dangerous fuel leak that the customer was unaware of. The plastic beauty cover on top of the gm 3800 series ii engines made contact with the high pressure plastic fuel line going into fuel rail. Due to high mileage of this car, line was damaged by the cover. Since then, I have seen 2 other gm 3800's with the same cover-to-fuel line contact. The potential leak is extremely dangerous as the leaking plastic fuel line runs from the firewall area, over the right side exhaust manifold, into the fuel rail on top of the intake manifold. A simple inspection & pad between the fuel line and the sharp edge of the plastic cover would be a very cost-effective cure for a potentially serious situation. This inspection & repair should apply to all gm badges with the 3800 series ii engines.
