20 Most Recent 2000 Buick LeSabre Questions & Answers

They are inside the plastic back attached to the trunk lid. To remove it there are nuts recessed in the back of the lid that have to be removed. The wiring pretty much keeps the back from falling but you still want to be careful. You need deep recess sockets to get to the nuts.

That can be a tough one to diagnose. I suspect they are not the only items in the car not immediately getting power, which suggests an intermittent problem with a master fuse or relay. If I were you, I would start by getting ahold of the circuit diagrams for the car (try Alldatadiy.com) and trace back the circuits from the brake and dashboard lights to where they reach a common fuse or relay and check those.

Is it the volume knob or the light that won't work? If the light, there is not much you can do as it is not user serviceable. A local Delco dealer may be able to fix it. Same with the knob ...

I cannot tell you what is wrong without diagnosing the problem. However, I can do this:

Let me give you a little "Automotive Technology 101". The first thing you need to do is to check what is missing when the engine dies. A gasoline powered, internal combustion piston engine needs 4 basic things to make it run:

1. Volumetric Efficiency (built into the design of the engine)
2. Air-Fuel Ratio
3. Compression
4. Ignition

Running out and replacing parts without first determining which of these things are missing from the equation is usually a waste of time and money.....your post bears witness to this statement.

The engine will not run at all if there is a serious problem with Volumetric Efficiency, and it takes an engineer to design and fix that anyway. It is not likely to be a compression problem if it starts and runs ok before it dies. So that leaves us with spark and air-fuel ratio.

So the next question is whether it is fuel or spark or BOTH at the same time? There are several things that can possibly affect each of these. Several possibilities can be either verified or eliminated by answering this simple question.

It is important to realize that BOTH of these things (spark and fuel) are controlled by your onboard engine control computer. To attempt to diagnose these things while ignoring the computer that controls them is usually a real EXPENSIVE way to perform this task.

With all that said,
What you need to do is check your fuel system and your ignition system when the engine dies. If the engine does not start right back up after stalling, it makes things a little easier because some "manual" testing can be used to verify a few things.

Check to see if there is spark at the spark plugs. Check to see if there is (A) fuel pressure at the fuel rails and (B) injector pulse at the injectors. This will tell you if it is a fuel "delivery" problem (fuel pump, relay, fuel filter, etc.) or a fuel "injection" problem (computer inputs, injectors, injector circuits, etc.) or if the ignition system is malfunctioning (coils, wires, computer, electrical connectors, security system, etc.).

From the sysmptoms you are describing, it sounds to me like if you were to actually check these things like they SHOULD be checked, you will most likely find that the fuel pressure is within specifications and that you have no injector pulse or spark at the spark plugs.

If this is what you find, then the "most likely" cause of your problem would be a failed crankshaft position sensor, because this will affect BOTH the spark and the injector pulse at the same time.

Proper diagnosis recommended.

I think you could use this manual method instead.. My nephew used it to repair my
car and it's perfectly fine now. Here's the website he bought it from. www.reliable-store.com

Does it have manual or automatic climate control . Do you know ? It's probably the blower motor control processor . electronically controlled . Your vehicle is the same as this GMC

Could be a bad coil, bad spark plug, bad fuel injector, however one cylinder will not cause a no-start condition. Plug the wire back in and see if it will start.

Have it scanned looking for diagnostic codes. Sounds like you could have a crankshaft or camshaft sensor problem, which will be a simple fix.

The neutral switch is located on top of the transmission under the hood.It is under the shift cable.Hope this helps.Good luck.

the problem is probably caused by wheel bearing leads (the wires that plug into) they often wear out I had the same problem once u find out witch side try cleaning the plugs wiping clean free the dirt , salt ,ect but on one side I just bypass the plug ran jumper wires that solve the problem sometime the computer will reset it self sometime you have to take posative cable off wait 5 mins reconnect this will reset everything

What was the code via the "service engine soon" signal?

2000 Buick... | Answered on Nov 20, 2017

bad connection to an abs sensor or a failing sensor.

Check the level switch at the back of the car - this turns the compressor on and off as the ride height changes. It may have come loose, is stuck or faulty.
