Question about 1993 Buick Century

3 Answers

1993 Buick Century satation wanon sudden stalling.

My 1993 Buick Century station wagon has a very frustrating problem. Sometimes you can drive it for days with no problem. Other times it is running fine and with NO warning quits. It doesn't run rough or flutter, it just instantly & suddenly quits. There seems to be no constant as to the reason for this. It can be idleing, in ''park'' or in ''drive''at a stop light. I can be driving along at ANY speed. Driving in a straight line or around curves either right or left, up or down hills or on a flat road. It can be in any weather. The gas tank can be full or near empty AND it just decides to quit. Sometimes it will start immediately or sometimes it cranks for like 5 minutes then it catches & will start. I have never gotten stuck with it YET but I think it's a matter of time! This car otherwise runs fantasticly and I hate to get rid of it. ANY IDEAS?????
Thanks in advance, Bob

Computer cars are hard to diagnose like this but i would suspect the fuel delivery system , stop by a "kinects" and let them scan your engine for a diagnostic code. always purchase a repair man. for these cars , it can be your best friend

My best guess is an electronic ignition that is warning you that it's about to go south, although they, in my experience, either work or they don't. A second possibility could be a loose or rusting battery cable which could produce the instant off behavior of which you speak. If any engine lights are on, take it to Advance Auto Parts and have them hook it up to their computer.

How long since a tune-up? Any applicable trouble codes? Two things off the top of my head, problem with ignition switch or intermittent rpm signal. I have no way to be sure?
When it stalls, does it quickly restart, if not, do some testing, see what your losing, fuel--spark--whatever.

SOURCE: 1999 buick lasabre hesitation while driving.

there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.

Check your fuel filter!

Check the EGR valve. Sounds like the three stage EGR valve is acting up. Look for any discoloration around the valve ports. This valve is located on the intake manifold near the throttle body.

I have a feeling your fuel pump is on its way out...but start by changing your fuel filter first, should be under $20....ie..not enough fuel getting through..

96 Buick Century stalls....


I spent endless time on this same problem on my 1992 Wagon. I changed out the computer but no help. It turned out to be the top dead center crank sensor that tells the system when the crank passes TDC. It is a small magnet essentially about the siz of a pencil eraser in the flywheel. it was cracked and occasionally would not "sense" and the car would just quit. troubleshooting was a nightmare because the computer diagnostics on the 1992 are less capable than the 1996 model. Anyway that is a relatively inexpensive fix and easy to know if it worked. Let me know how you solve this.

1999 Buck Regal Stalls While Driving


Possible solution to stalling '99 Buick. My '99 Buick Century would die for no apparant reason with no error codes. After 4 days at a Buick dealership and many frustrated mechanics, the problem was corrosion from under the battery location. The wiring harness had small amounts of corrosion internally. Check the wiring under the battery for any corrosion. This has been the problem on more than 1 vehicle that we are aware of. No service bulletin has been issued by Buick.
