Question about 1994 Buick LeSabre

1 Answer

1994 Buick LeSabre 6 cyc will not start after running fine

All of the sudden, without warning, it won't start. Sometimes it will start right before or after the tow truck shows up. One time, a mechanic put in a used anti theft module. I had to get new keys. I finally decided to just leave a key in the ignition all the time. My thinking was that it would reduce the chances of the car sensing the "wrong" key and shutting off the fuel system. That worked great until I bought a new battery. It is like the car lost its memory. I am sitting here stranded at work.

    Loringh,

    First of all, thank you for the attention and the quick response. I called my mechanic and he said "resetting the computer" was the first thing he tried. No luck. Any other suggestions?

Disconnecting the battery (to replace it) has obviously reset something in the computer. I would suggest you call the service dept of a Buick Dealer and ask them how you can reset the computer. They are usually pretty helpful in a case like this

Good luck

    Not to be disrespectful to your mechanic, But a "mechanic" is different than a service man at a Buick
    dealership. I have found these dealer folks more than helpful. Once I had a problem with an F 350 that was ready to make a customer delivery (trees & shrubs) and the stop/taillight would not work. I called the service dept of a local Ford dealer, asked for the service dept, explained my problem and he went and got a manual, looked up the info and told me to check the fuse in column 3, row 5 and sure enough that was the fix. The worse thing that they can say is sorry we can't help.
    Other than that, not being there, that's what I would do.

    Good luck

If the motor gets hot and cuts off and will not start for a period of time the problem would be the crank sensor. The sudden cut off and starting right back up can be due to dirty battery cable connections. Remove them from battery and clean all three of them with a wire brush and replace both bolts.

Car runs fine just quits


Does this have a "Check Engine" or "Service Engine Soon" light on? If so, get the codes pulled and post them back here along with the engine info. If no codes are present then it may well be a bad crankshaft sensor. I have seen many of these give intermittent problems (usually heat related) and do exactly what you have described without setting a code.

URGENT - 1994 Buick LeSabre stalls in mid-ride


I have the same vehicle, and had the same problem. I took it to my mechanic, and after all of the codes were read we replaced the Ignition Control Module, then the Crankshaft Position Sensor.

It runs just fine now.
Best bet would be to have someone hook up the code reader. The car will tell you what it needs(not specifically, but it'll tell you where to look).


Good luck!!!
