LeSabre :: 1989 Buick Not Starting / No Spark On 4 Cylinders
Apr 26, 2014
I need getting my Buick to start. It is a 1989 LeSabre Limited with a series 1 3800 engine. I only have spark on cylinders 3 and 6 (paired on ignition coil). I have run tests to see that I have that I have 12 volts to the ignition module, 12 volts out to the crank sensor, signals coming from the crank sensor. I pulled the coil pack and found that I only have a signal on the blue wire supplying 3 and 6. I don't get a signal on the green and yellow wires supplying the other 4 cylinders. My tests would indicate that the ICM is bad. I replaced the ICM and out of desperation the coil pack and I still have the exact same problem. I cleaned the aluminum surface to make sure I have an excellent ground.

I have a 1989 Buick LaSabre that is having some problems and no mechanic seems to be able to figure it out. After 4 computer items totally $1,800.00 since March, the same problem started again yesterday. I am driving through the hills to town and the dashboard lights all come on and my engine cuts out. I stop, put in park and restart and take off again. As soon as I am on the highway, car runs fine. It has something to do with the fuel system I believe because once it cuts out the car smells like lots of gas but after it starts back up (and it does every time) the smell goes away.

I just finished rebuilding my 1990 2.9 and it wouldn't start. When we did the initial start up, the truck needed ether to start and ran decently while stumbling. I found out that the spout connector was removed from the previous owner so I spliced it but still no starting ...
I installed a new fuel filter, fuel pump, cleaned the injectors, spark plugs, spark plug wires, distributor cap, rotor, air filter and cleaned the MAF. ..
Its not a spark problem because I'm getting good spark from all the cylinders and yes the timing was set correctly. It sounds like it wants to start but just doesn't have something to make it boom. There are also no codes...

I have a '98 Buick LeSabre, 112,000 miles and it's white. When I put the ignition key in and turn it without starting it completely I get a humming noise coming from the rear of the car. It lasts about 5 seconds and stops. When I start the car it begins again and continues all the time I'm driving. A friend suggested it might be the fuel pump.

Every 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?

89 2.3l 4x4 will crank just fine but no start. It is getting plenty of fuel. Replaced ignition module,crank sensor,computer, checked all fuses. I've been looking for a broken wire with no luck. Doesn't seem to be getting any power to the coil packs. Truck was not driven very often until a month ago. Started up fine everyday until the no start.

My Lesabre is a good car, it drives just great. It has lots of power, no performance loss with this problem.
It has an incessant rattle, when I try to locate where it is coming from, it sounds like it coming from everywhere. Like it echo's throughout the engine. Although it sometimes seems to come from the passenger side where the belt system is. It has one of those serpentine belts, the one piece runs all. I have changed the idler pulley, the belt, the power steering unit and pulley, water pump and water pump pulley, alternator, removed the metal spash guard under the engine all to no avail.

I have recently noticed that my car will stall out when I get up to about 20 mph. My car starts fine, no check engine light on. I has a tendency to just die in the middle of the road at times too. I have changed the spark plugs, spark plug wires, and a new fuel filter. Do I need to change the mass air flow sensor? Or the crank position sensor? I have no problems starting the car either. Runs good when it runs.

1994 Mercedes C280, Cylinder 1 & 6 no spark. Changed 3 coil packs, changed wires and spark plugs. Engine wire harness look fine. Cylinders 2,3,4,5 have spark. Coil number 3 Controls Cylinder 1& 6; and I use multi-meter to check for voltage. 11.70 volts with key on position, 13.80 volts with ignition on. I need to figure out could it be a sensor or the ECU( Computer) or Engine?

1996 buick lesabre custom 3800. The car stalls from time to time, and the fuel pump, power windows, power seats, and power mirrors all stop working. Most people who have had this problem cleaned the ground bus on the drivers side under the carpet. I have done this, and the car has not stalled yet, but I haven't driven it far because I have noticed the fuel pump relay and power windows relay are getting extremely hot to the touch after 5 minutes or so of driving. Why these relays are getting so hot? I cannot afford to keep getting the car towed home.

My 2001 Buick Lesabre has always shown to run exactly normal on the temperature dash unit until recently. I checked my coolant level and it was a bit low, so I added. After I filled the radiator I have noticed a coolant leak spot on my driveway, after I drive it now. I have removed the gravel shield and have tried to pin point exactly where the leak is coming from, but cannot. Now, each time I park, after driving it, I put a clean piece of cardboard under it to try to see exactly what area the leak is coming from. Last night I put the car on ramps and crawled under to discover that the leak is located just above the oil filter and is actually dripping from the oil filter, but I still cannot see the exact location of the leak.Actually the leak does not appear until about an hour after I park the car, so it sounds like something is contracting after the engine has cooled off, but what? The leak has seemed to be getting worse each time I drive the car. How can I determine exactly where the leak is coming from without just changing a bunch of parts.

I currently have no brake fluid in my car because it keeps leaking out (leaks while actively being used). The leak is between the power brake booster and the brake master cylinder... Is there any type of gasket I can get to better fill the gap between the two pieces of metal? Is there some way to tell which of the two pieces is creating the leak to narrow down which to purchase?

My 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.

My '98 Buick's AC works well when I take it to a mechanic. But when I leave after they say, 'it seems fine now,' a few miles later the cold air starts blowing through the defroster vents, still nice and cold. Then it comes back down to the dash and then goes back up to the defrost. But sometimes it stops blowing altogether, it doesn't blow anywhere! Nothing, not even warm air. And then later everything is fine again, until it happens all over again and I take it to another shop when I hear 'it seems fine now.'.

I have been to a few different repair shops for my 2000 Buick Le Sabre shimmy problem with no luck. I have a really bad shimmy, while accelerating between 45 and 50 mph, and it seems worse on an upgrade. Past 50 mph, it smooths out. Over the past several months, mechanics have checked the balance of my tires and rotated them, done front end alignment, rear alignment, replaced the right lower control arm, the right sway bar link and the right wheel hub. Still no luck, so it came down to the determination that it must be a bad tire. Now I have 4 new tires (it was soon time to get them anyway), and I still have the shimmy. What else can we look for? My local mechanics seems stumped. I have not taken it to a Buick dealership, however...

Driving my car over the week-end and experienced a lot of hesitation when I stepped on the gas. The car seemed to delay in kicking in to the next gear.I stopped and checked my transmission oil and realized I didn't have much transmission fluid, practically none. So, I added a quart. My question is what should I do now. I know it probably doesn't have enough but I don't know how much to put in. Or should I just have it changed?

I 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.
