    My aunt's 2000 LeSabre has the exact same problem except very infrequent. No codes, only at low speeds, and two mechanics have been unable to replicate the problem over three weeks of trying.

    Did you ever get an answer? Thanks for any help you can give.

    After I replaced the transmission the battery drain went away. Had an error code about a solenoid on the transmission prior to that. I have a 97 Buick with 220,000 miles that hums right along.

    I had something similar happen. No fuel pressure. Had to replace the pump in the tank. Not Cheap, not something for the home mechanic. I shouldn't have it let run out of fuel. I'm glad my 300 lb neighbor lady was around to push it back in the driveway. Holy cow was she strong!!! Anyway, I'd start and replace the fuel filter first. You can buy a fuel pressure tester and know for sure.

    Some of the auto box stores (Autozone, Oreilly) will loan a fuel pressure tester.

    I didn't see this issue posted. My 4wd must stay in Auto 4WD. If I put it in 2H it goes thru the gears and when it hits 4th gear it drops to neutral. I am unable to drive in anything other than Auto 4WD. The last time I used the 4WD function was approximately 5 months ago and I don't recall putting it in Auto 4WD. I have very little call for the 4WD but I like knowing I have it. I recently went from NM to KS without realizing it was in auto 4WD. That was when I found that
    the 2H wasn't working. Any ideas? I am unable to locate the ATC fuse that one message discussed.

    You have this post in a leSabre discussion. So I think you should post in

    You should find someone there to help find the fuse you want to check and to find more about the transmission's behavior.

    Good luck.

    check the fuel pressure regulator. if the vacuum hose attached to it has gas in it when you remove the rubber elbow it is bad and needs replacing. they go for 50.00 bucks or so.you'll need special snap ring pliers and some petroleum jelly for the new o rings. a five minute job. good luck
