My buick has a weird problem, basically it wont start the security light comes on, nothing and i mean absolutely nothing works inside of the car and the power window circuit breaker under the back seat is burning hot, obviously its an electrical problem but I am thinking its the body control module but I want to be sure .... what it could be?
View 5 RepliesEvery once-in-a-while I've noticed a "security" light is illuminated on my dash-board. When this happens, I can't start my 92' Buick LeSabre for about 5-minutes or so. Aggravating, to say the least. Is there something I can do? Including "disabling" it?
View 2 RepliesMy wife stopped at a local store(car running tip top as usual)turned off the car. As she came out of the store after about 20 mins. NO START! Security light is flashing all interior lights,radio etc work but NO headlights and if you turn signal it blinks real fast like a bulb out condition! The fuel pump does its prime up etc. NO CRANK,after say 15 seconds security light goes out,still NO CRANK!I did 10 minute reprogram(key in accy for 10-20 min) -no change!I also tried the valet key!NO GO!!!
I know GM had a few security problems but I have been out of the mechanic loop since losing the use of my legs!

I first thought my issue might be the ignition switch or maybe the neutral safety switch but through some info I've come to realize that my issue appears to be from the anti theft system. I did a test where I turned key to start and backed off to run and then leave car for 10 minutes. I did this 3 times and it was supposed to go around the security system and then try to start but it didn't. I went through two trials with the same result. On the first of 3 times in each of the two trials the security light was not on but the 2nd and 3rd times it stayed on. I've heard this problem can be nearly impossible to trace and repair.
View 10 RepliesI purchased a nice 03 Buick lesabre with only 40,000 miles mint , well after driving and enjoying it now for 2 months, I now have a red flashing light left top side of my radio. However it still works and it does go off when I start the engine, what does this mean because I pulled out the manual and this is what I have, is it a normal thing that was just delayed in happening for some unknown reason?

Ok, got a 99 Buick Century that is a cantankerous old hag. It doesn't like to start sometimes. naturally when i really need to get somewhere. The security light blinks at me for a while, goes solid, then i cycle the ignition and hope it will start. It happens with multiple keys and remote start(which has been removed multiple times because each mechanic thinks that will magically fix it). No rhyme or reason, it sends no code, the local buick dealership couldn't figure it out. I think its my security computer. what is the easiest/cheapest diy solution besides get full coverage and leave it in the ghetto with the keys and hope it ends up on cops? battery is fine, it starts normally most of the month, just maybe a handful of times a month it won't. Starter I believe is still good as well, and gets voltage when it starts. Fuel pump audibly works all the time.
View 4 RepliesMy car would not start yesterday, and I realized the fuel pump was not running. So I bought a new fuel pump today and put it on, the car still won't start, the fuel pump still does not run and I have been told to check the relay. I cannot find the relay for this car.
View 7 RepliesI have a 2002 Buick LeSabre. Back information is this. the car has had a coolant leak for years, very slow though. Last night while working (I drive for a living) the thermostat climbed up to hot and then immediately went back down to the middle range where it normally goes, so I thought I was fine. It then climbed back up and staled out. It started again nearly immediately and I made it back to my work. About 30 minutes later I began to drive home. The temperature gauge started to climb up again, and then immediately went back to normal running temperature. I kept an eye on it.
About 2 minutes later it shut off completely. I had dash lights, head lights, and emergency flashers. Trying to restart it killed my battery and I had it towed home. This morning I put water in it (it was a gallon low even though I had filled it three days prior). I got a jump start but the car wouldn't start. It cranked and cranked but would not start. I did notice a leak of water from near the bottom of the engine. I am curious as to what the problem may be and why it is not starting now.
The car (97 Buick Le Sabre with 3800) ran fine and started fine until one day last week it did not turn over. After about 10 minutes it was tried again and this time it did start. It was used regularly with no issues for the next few days. Then one morning it didn't start (or turn over) and hasn't really been successfully started since. The battery is good and cable connections too. So my mechanic figured it was probably the starter. Since I had this weekend free, me and my friend replaced the starter. But it still did not start. We then turned the ignition to run and crossed the solenoid terminals with a metal tool and then the engine turned over and ran for a brief period (around 5 to 10 seconds) but then killed.
This procedure was duplicated a few times. So we figure it wasn't the starter, the battery, or most of the larger cable connections. The tension wheel had failed on it in the recent past so we wonder if when the belt blew out if it had hit and weakened a wire somewhere that has now failed but difficult to locate. We also wonder if the car's security system maybe failed and it thinks the car has been stolen. This might explain why it won't start or stay running when ignition is circumvented. Note: the panic button on the key fob works properly. All of the fuses were checked and none were found to be blown out. What the root cause of this problem might be and how to repair it?
1996 Buick Le Sabre. About 1 time in 10, the car will not start. The starter is fine; seems to get no gas. Took it to garage for diagnosis. They could find NO problem: but replaced plugs and wires anyhow. Car still refuses to start -- just about 1 time in 10. It seems to have a bigger problem if the car was parked going UPHILL. This is not always the case. Is it likely to be the fuel pump? Is there no way to check this without simply replacing the fuel pump?
View 4 RepliesFor the past few months security light of my 2003 Alero keeps on activating preventing the engine to start or it doesn't even crank.
I always do the reset technique..."Turn ON the engine key for about 20 minutes and wait till the flashing security light become solid before starting the engine." Today when I started the car the security light comes ON and stays on for my whole 50 Kilometers travel. When I reached my destination,I tried to turn ON and OFF the engine waiting for my luck to have the solid security light to come OFF,but no luck.
Will this problem have any effect on the performance of the car? Will the car stall while I'm on the road?
I have a 2001 Buick LeSabre (Limited), with 101,000 miles. It runs great and a very reliable car except:
After going for some driving in town during a warm day (60 F or above) doing business, the engine gets warm but within normal temperature range, and after making a stop to get groceries for eample, I have to be very careful when starting the car again. If I let the starter go for more than a quarter tourn (crank), the engine gets week and acts like it is flooded with gas, just like when we had carburators in old car and it dies after a few shakings.
So I have to wait for 15 minutes at least before I restart the engine but doing so I have to be really careful again not to let the starter crank for more than a quarter turn. However, this problem does not happen during cold weather days (say below 40 degrees F). What is going on with my car?
My dad has a 98 Buick La Sabre that will shut off at times. It once shut off as he was turning on the air cond. last summer. Right after it stalled and would not start he attempted to open the windows but they would not work. After a few hours and cooling off it started and the windows worked again. He took it to a shop who said it was the map sensor. They changed it but the problem happened again a few weeks after. The fuel pump has recently been changed along with the fuel filter.
One mechanic suggested it could be the ignition control modular or knock sensor. He recently got a different car so I an going to test drive it for a while. If it shuts down I will test for spark to confirm it is not a fuel problem. I will also try swooping relays to see if that is not the problem. I will be cleaning all the connections I can find with contact cleaner as it can't hurt.
What could be the problem. Could it be a short, a bad wire that once it gets to much of a load on it cuts the engine off?
My friend has a 2003 Buick LeSabre 3800 with approximately 80000 miles. He complains that the car will die while he is driving. I work at a local parts store and have access to code reading scanner. We've checked the fuel pressure at fuel rail several times and is okay. The only thing that seems odd to me is that he says the tach will quit working. It dies like the switch has been cut off. He can wait, sometimes 10 to 30 minutes, and the car will restart. I had him to come by work when the car acted up so I could scan it. It gave crank sensor out of range, and indeed the tach was not working. I turned the car off to scan, and restarted. The tach was working.
View 2 RepliesI have a 99 Buick LeSabre and it died while I was pulling into a parking lot. It wouldn't start back up. I tried listening for the fuel pump and nothing. It's not priming or making any noise. Once I got it home I replaced the fuel pump relay. Still nothing so then I changed the fuel pump. Still nothing. I'm stumped. I'm going to check all the wires tonight to make sure I got them on right. Is there any other relay or fuse on these cars that I can check?

View 1 Replies Having a problem with my 1997 Buick Lesabre. It's a v6, automatic 4 door, and I live in good ole HOT Florida.
Anyway for about two weeks ago I went to start up the vehicle and it would turn over, run for about 2 seconds, and then turn off and did that about 5 or 6 times. Knowing very little about cars I had a friend try to jump me, and nothing, still wouldn't turn on. So I left the car there, came back five days later. It started and ran, and I drove straight to the mechanic. I had noticed my belt whistling a little so he put on a new built, fix a power steering pump fluid leak, and put on a new belt tensioner.
Anyway, I pick it up a week ago and it starts up no problem. Today the problem has started again. Some times now though it will start up, run for a little while and then just shut off. Doesn't seem to make a difference whether I am idling or not. Sometimes now though it will turn over, but not actually fire up and start.
I have a 1994 Buick LeSabre Limited with a 3800 engine.When the engines cold,it starts fine and drives fine.When it reaches operating temp,if you shut it off. It will crank but not start back up until its cold again. I've replaced the crank and cam sensors but no change.
View 2 RepliesBack in April, I posted this comment about occasional skipping when accelerating: "I have a 2003 Buick LeSabre with 187,000 miles (mostly highway) that skips/jerks sometimes when accelerating, even when in cruise control. It only does this every month or so; and, of course, never does it when the mechanic is in the car. No warning lights have ever appeared and my mechanic says no codes have shown up in three diagnostic tests.
In the last 1.5 years, the following items have been replaced: power steering rack, oil pressure sensor, FE control arm bushing, intake manifold gasket, oil pan gasket, transmission mount, water pump, rear struts. In 2010, an alternator, thermostat, mass air flow sensor and front brake pads were installed. Oil is changed as scheduled; tires are rotated as required and car is serviced at the first sign of any problem. Other than occasional skipping, car is in pristine condition and rides like a charm. The most recent skipping occurred March 29th when I was 200 miles from home. It lasted sporadically for about 10 miles and did not occur in the other 190 miles."
Based on the advice of responders, I had the fuel filter replaced and the car never skipped again ... until today, three days after the rotors and brakes were replaced. Like before, there have been no warning lights and the skip, which can occur when braking or when in motion, occurs sporadically. It might happen several times in a mile and then not happen again for some time. The car now has 192,000 miles. Is this the transmission, a problem with the recent brake installation or something else?
I have a 93 Buick Lesabre and the ABS light was coming on and off for about three weeks.Now it stays on all the time. Just recently I had the brakes completely lock up on me. In my car you have to apply pressure to the brakes to even get the car to shift into gear. The car will drive for about a mile and then all of a sudden the brake pedal is completely hard and the car will not roll forward. It does it completely fine in reverse. My calipers are good and there is no sound of them locking up. The pads are in good condition.Then after this happened to me twice in a two mile drive, struggling to get it home... now a light in the dash flashes SECURITY. It is strange and I know my brakes are in good condition and there is no abnormal wear and tear.
