I have a 2006 Buick Lucerne, 3.8 liter, automatic with 42,000 miles. Some days it runs like like a champ then other days, it will stall literally when I may be driving 20 mph or 50 mph or any speed... Also, it may stall when I'm stopped at a red light but not every light either. More often than not it starts up fine but occasional it will start but it just doesn't hold an idle but then eventually it does...I was thinking a fuel issue like maybe a fuel pump that's going bad and my second thought that it could be the brain ...Any ideas or suggestions???
More often than not on those. It's a bad fuel pump or clogged fuel filter. I would change the filter first. It could just be that. But if not you can pressure test the fuel pump
Thanks Scotty...And I haven't even done any research yet on replacing the fuel pump or fuel filter cause I'm pretty sure I'll have to drop the gas tank if it's either one....Ugh...Driving this thing cause the 2 cars that I had drowned...Dam you Hurricane Ian!!
Scotty, still dead in the water with this Buick.
I saw another video regarding the Lucerne and apparently there's an issue with the Fuel pump relay in the fuse box being shorted out due to the rear seat bracket pressing down on it...I replaced the relay and she ran great for 2 days then I was back to square one...Figured it had to be the fuel pump so I installed a new one, still at square one.
After even more research, apparently the fuse box may be the issue...Guess that's going to be my next purchase...Uneffing believable...Can't win.
