However, there are some reasons that can be easily identified. Just like knowing why your car won’t start after stereo installation! So, knowing the cause comes from a proper diagnosis.
To ease your pain, even more, I’ll mention the specific Buick model here and there. That way, you’ll know clearly about that particular model’s problem and respective solution.
However, if you customize your LeSabre like this one there can be issues if not done right.
I think you got my points so far. Let’s not stall the discussion further and look at the 4 probable causes.
Reason 1 of 4: Crankshaft Failure
As mentioned in the introductory text, this sensor problem is prevalent in most Buick models. If your 1995 Buick LeSabre stalls while driving, then this is probably the cause.
You’ll notice some odd issues such as the abrupt power disconnection, and warning light signals. These are some of the symptoms to know that your crank sensor has gone bad.
So, what can you do in this type of situation? Let’s see what can be the possible solution for this issue.
Solution
Often users misdiagnose this particular issue. They think it’s the cam sensor that’s causing such ruckus. However, that is completely the wrong way to think. It can be the sensor or it can be the whole crankshaft.
Before you change any of your car parts, you need to understand the problem. Otherwise, you might do more harm to your car than good.
Now, let’s actually solve it. If your crank sensor is bust, then you’ll need a new crankshaft. There’s actually no other way around it.

Along with the sensor, you’ll have to change the timing chain and some associated gears. If you change all of these components, you should be able to drive your car smoothly!
Talking about sensors, it can be tough to find the right sensor for your crankshaft.
In that case, you can try out these compatible sensors with your Buick LeSabre.
- The all-time famous ACDelco Professional 213-4665 Engine Crankshaft Position Sensor.
- DOICOO Crank Crankshaft Position Sensor 10456161 213-151. It fits with all sorts of cars as well as the LeSabre you own.
Reason 2 of 4: Damaged Plastic Intake Gasket
Let me tell you beforehand. This cause is not quite as common as the others. Why is that? Because only a handful of 1998 Buick Lesabre stalls while driving due to this issue. Still, if you have a 1998 model, this one’s for you.
When you mix something like antifreeze with your oil, you’ll notice the stalling. Because it leads to severe damage to your plastic intake gasket.
So, how to fix this issue?
Solution
This solution is similar to the previous one. Yes, you guessed it right. You’ll need to change or replace your intake gasket with a new one.
The most upsetting thing is the hefty cost. That’s why you can try all by yourself to set up your intake gasket with FEL-PRO MS 98014 T Intake Manifold Gasket Set.

But if you decide to take it to a mechanic then you’ll have to pay around $700 to fix the gasket. That’s quite the expense. However, if you’re well-versed with car mechanics, then you can save the servicing fee.
Reason 3 of 4: Fuel Pump Problem
Your Buick might not have problems similar to honda accord making grinding noise while starting.
However, the Buick has come with severe complaints about the fuel pump system. A bad fuel pump can be the most dangerous thing for your car.

Your fuel pump relays the pressurized fuel to the rails. So, if the fuel pump fails to do its duty, it can choke your engine from time to time. Consequently, your engine will start and then lose power.
So, how can you solve this difficult issue?
Solution
Your fuel pump does not fall under constant monitoring under the engine. So, you’ll need to go through the whole troubleshooting process manually.
First, turn the key on and listen for any noise. If you don’t hear anything, then you can be sure that the fuel pump is not in mint condition. But you can do an extra step to be absolutely sure.
You can borrow an ear to be as thorough as possible. If the sound is still not heard, there’s no denying it anymore.
In such a case, you can get a new fuel pump system for your Buick Lesabre. I know you don’t want your car to suffer anymore.
That’s why I’ve spoken to some veterans who own this marvelous ride. They all had to change the fuel pump on their ride at some point. So, here are the recommendations-

Reason 4 of 4: MAF Sensor Failure
Last but not least, another sensor failure problem. 2001 Buick LeSabre stalling problem is majorly caused by this particular reason. But that does not mean other Buick Lesabre models can’t fall victim to it.
Just like the crank sensor, the MAF sensor is equally important for your car. It can get affected by debris or other conditions.
How do I detect the problem with the MAF sensor? By getting a proper diagnosis by locating the trouble codes Buick LeSabre P0101 or P0102.
Now, what is the solution for a faulty Buick MAF sensor?
Solution
