You need to diagnose the code. Take it to an Autozone or Advance Auto or other place where they will read the stored codes free and the current codes and tell you what they are. Do not buy anything or replace anything until you post someone and someone knowledgeable tells you what may be the true cause.
 
A light can be the gas cap not sealing, but it usually doesn't do the check so that it would turn the light off on a restart. Leaks in the pressure sealing for the gas vapor system are common problems. The code check at a store will help.
 
I Have read in other forums that some 1994 and 1995 Bonnevilles have problems with the computer more often than is common ont he H-bodies (Olds, Bonneville, LeSabre, Park Ave, Olds 98). Replacing the computer helps.
 
The stalling and restart can be the crankshaft position sensor, which may not give a code.
 
You didn't mention how many miles on the car. You can also have trouble with MAF sensor and throttle position sensor wearing after lots of miles and years.

I was wondering if your stalling issues have been corrected, and what exactly fixed it? I have a '91 LeSabre (Clifford, the big red car) and in April, it suddenly started stalling, and my mechanic and several colleagues have not had success in honing in on the cause. It is due for inspection, and I will need to donate it, even though it only has 59,000 easy miles on it.
 
I know that the computer and many other parts were replaced (then he put the original parts back when the problem wasn't resolved).
 
I would love to know if anyone has discovered the solution
 
Thanks much

For both of you another suggestion is to have a fuel pressure gauge put on the car and taped to the windshield where you can watch while driving and see what it does just before the stall. Some have said fuel pumps are a problem in stalling. But there are others.
 
Several people suggest that anything other than Delco replacements have given trouble in several months.

Cannot say if problem is fixed or what happened. My son had driven it and it stopped stalling. Has not been any problems since first reported. Sorry I cannot be of any help. Go figure.

Thanks for the fuel suggestion - I'll talk to him about it.
 
Tally, did you replace anything in your quest for fixing the problem?
 
This is an extremely frustrating problem - the car has basically been at the shop since April! Fortunately, we have other vehicles, but I hate just junking the car over this - I would at least like to sell it for something.
 
Any other suggestions are supremely appreciated

Son finally got buick fixed, He took it to the dealer, and the problem was the coil. Only running on 2 cylinders. Cost $171.

Well, the good news is that the problem was fixed. The better news is that we found a 2004 Civic for our daughter and sold the Buick, in running condition and ok.
 
Turns out the problem was two fold, with the coil (I think) being the first - the NAPA part works for all cars except the '91, where there are issues. While that 'bad' part was in the car, our guy changed the computer, and that didn't correct the problem, so he put the old computer back in. With changing other parts, he and a buddy finally determined that the NAPA part was no good, and got me a used one. Then another buddy suggested trying to replace the computer again, and that turned out to be the second part of the problem - both parts simultaneously were bad.
 
Thanks for all the assistance!! Happy New Year!

#106 of 282 my 1993 buick lesabre wont start and stalls by mistynd123

Jan 27, 2009 (1:55 am)

recently i just bought a 93 buick lesabre and it has94,000 miles. I am having problems with it starting. and the check engine light comes on, and sometimes by putting it in nuetral will get it to start, but that doesnt always work. also by pushing it, then turning the ignition on it will start but not always. Also it will stop while i am driving it usually it will start right back up but not always. weve already had the fuel tank censor changed, and the fuel lines changed and theres still a problem.
ive read online about alot of cars with the same problem but i cant find a solution.
My husbands mom used to own another 93 lesabre also and has the same problems. any help would be appreciated

Have your mechanic test the computer. That's what was our ultimate problem, and because it was so intermittent, it mimicked other stuff. But make sure that they can return it if that isn't the problem. It's around 300 to replace. There was another part (see my post for what they looked at) that was bad, so it was the combination of the two.
 
Best of luck, Clifford has gone to live with a new family, so I don't have him anymore.
