I would have the battery checked if you haven't replaced the battery in a while. This is if you are sure that the fuel delivery is ok. Electrical is the other problem for non-starting cars.

SOURCE: 1995 Buick Lesabre: security blinks and car will not start

If the starter is turning the engine, try re-setting the security system (leave key on till light stops blinking.) If the starter does not turn, you may have some success in re-setting system, if not you need to check battery voltage and voltages in starter system till you find the problem...can be something as simple as a bad connection at the battery. If you need help with further testing, just ask.

SOURCE: abs & traction light on 1997 buick lesabre

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.

SOURCE: Buick LeSabre makes funny sound!!!

It is a sign of a clogged convertor, but i happen to own the same car (with a series 2 3800) and had the same symtpoms going on when i bought if for the wife. Mine turned out to be a Exhaust Gas Recirculation Valve (EGR Valve).

To kind of get a feel for what is going on with the convertor, you can have someone help you but sitting in the drivers seat, with the car running. You go behind the car near the tail pipe. Now have the other person rev it up a little, not to much though. Put your hand but the tail pipe to see what kind of pressure the exhaust has. You can use another vehical to do the same thing to feel what things are supposed to feel like. If the convertor is plugged, the pressure of exhaust coming out will be a lot softer than it should be.

If after checking it as discribed above, if you feel it is plugged, grab a hammer, and bang the heck out of it. This will break up and loosen the clogged part without have to replace it.

There is no really good way to test a EGR vavle without a special computer. Replacing it however, does seem to me as the most likely repair for this vehical. It is located on the top of the drivers side of the motor. It look like a cylinder with a wire coming out of the cap, and is held on by 2 13mm nuts.

Good Luck....

SOURCE: 2001 Buick LeSabre, 175,000 + miles. Won't start

Your cars problem lays into the electrical system only. Wetness is causing a short. When you turn the key on and off for so many times the connections to the battery and starter get warmer each time in turn dries out the connections the contact is made so it will start.
If the car will not start at all when wet the plug wires would be at fault. Yours does start as you state so the wires are fine so far. I would check the connections of all wiring to the starter, battery, & alternator making sure they are corrosion free and tight

The fuses and relays are on the back fire wall under the hood.Just remove the plastic cover.This is not a fuse problem but more than likely a bad battery or charging system problem.Check the battery.Have it load tested and have your charging system tested also.Make sure all the cable connections on the battery and alternator are all clean and tight.Hope this helps.Good luck.

97 buick le sabre turns over but wont start


Good Morning,
The coil pak is usually the problem with these buicks. You can buy a new one at your local auto zone store for around $50.00 and you can install it yourself in about 20 minutes! It just might be a quick fix without paying a mechanic to diagnose it. If you decide to install a new coil pak remember to disconnect one side of the battery first and above all only replace one spark plug wire at a time. Please let me know if I can be of further help and thank you for using FixYa!
