Question about 1995 Buick LeSabre

1995 buick lesaber dies intermittently

I just acquired a 1995 buick lesaber from my grandfather, long story, but i have recently began experiencing problems with the car dying. the car in question has only 32000 miles to it's name and it really does not care if you are in the driveway or on the interstate, it just shuts off. Luckily it restarts every time, and i am at a loss as to the cause of this. It does not stutter as in the effect of low fuel pressure, the lights will dim, speedometer will go whacko, then all the lights come on. it is almost as if there is a sever draw on the alternator, and it just will not cope. i have also found that it is worse on a hill as opposed to flat ground but it really does not matter. there is no lack of power, the car still runs fine, until it just up and dies. i have searched the forums throughout the internet and have found several cases of the same problems with little or no help on the issue. i have contacted Buick to check on recall notices that my grandparents might have missed and nothing, although they did say that since my car had such low miles they might be able to provide some repair assistance in the pocketbook area. fuel pressure fine with 33 psi, voltage fine with 14.45-14.04 there was a few times that the voltage dropped over a volt and a half, but it was rare. there also seems to be a significant load on the motor when the ABS motor kicks on. any suggestions? if more info is needed i will be glad to provide it.

    i have tested the vacuume and it did seem to be a little low at the time, but as the engine warmed up it got better. also this morning it was really cold and the car would not stay running to save its life. this would be a possible solution. i will try it and get back to you thanks again

    95 LeSabre sometimes runs good, sometimes won't hardly run at all. When
    turning the ignition to the 'on' position, both fans come on when the
    engine is stone cold. After starting, will idle erraticly but runs good
    once you step on the gas. It might run great to the store and back, or
    just decide to die while driving down the road. I suspect the ECM is

Make sure the battery terminals are tight. These cars have a double stacked positive side terminal that, to get tight enough, usually means stripping the threads on the battery. After fighting with this connection for more than a year, I finally put an old fashioned post adapter on the positive threaded side terminal, then put another 'marine' adapter on the post. After stripping the rubber insulation off the two positive wire's terminals, they'll stack up on the marine post and wing nut them good and tight.

I would suggest testing the vacuum on your car, not only check your vacuum lines, but check for vacuum leaks at the throttle body / carburetor, intake manifold. As the gaskets get older they sometimes erode away and get the smallest of holes in them and they will shrink and loose vacuum causing this particular problem. Another thing that can cause this to happen but this is generally only when the engine is warm is the module on the distributor and it usually requires a few minutes to cool down. Good luck and I hope that this helps you. and remember to take the time to rate all solutions that you receive.

97 Buick lesaber runs good all sudden dies wont run Windows won't go up or down?

When it suddenly dies an wont run , is this a permanent situation or will it start an run again at a later time ? Do the windows not working only happen when it dies or is this all the time regardless of vehicle suddenly dying ? When it dies you have to find out what is missing Fuel , spark etc.. Find this out an test the appropriate system ! Check all wiring harnesses underhood for proper routing an no bare wires touching ground ! An do a wiggle test on the wiring harness with it running or with someone cranking over the engine to see if it acts up or starts ! How long does it run before dying ?

Replacing tensioner pulley spring on a 1997 buick lesaber

you purchase a whole new tensioner assembly and bolt it in where the old one was. that way everything is new. if the serpentine belt has never been changed, this would be a good time to do that too as it has to come off in order to remove the old tensioner.
