Question about 2000 Buick LeSabre

Intermittant starting and stalling out problems

A good friend of mine has a 2000 Buick LeSabre that is for the most part a really nice car. The problem is that 9 out of 10 times it starts up just fine but sometimes it just keeps turning over and over and doesn't fire up. Also it sometimes will just stall out while sitting at a signal OR even driving down the road.
To me the way it gives no warning and there seems to be no pattern I am guessing it is some kind of a sensor or something with the computer. But I am not a mechanic and the mechanics she has taken it to have not solved the problem.
I personally do not know what else could cause it to act this way.
I used to have a Ford Bronco 2 and it was doing the same thing and it was the ignition module. I was wondering if this make and model of car has one of those, if that could be the problem, if it could be a fuel system sensor or problem, and if it is common with this vehicle. Otherwise what would be the best way to narrow it down.
I am really hoping you can help. This young lady just recently purchased this car and it is her only means of transportation for getting her son to school and herself to work. Please let me know what my/her best course of action would be.

I'm hoping the mechanic checked this but...sometimes the obvious will get over-looked. I have seen this a few times myself.
Remove the battery cables at the battery and clean them really good. You can purchase a little battery tool at any auto parts store, it has an end to clean the battery terminals and one to clean the cable end. If your not comfortable messing with this, you should have someone who knows a little about cars take care of it for you. Sometimes just those cables being loose can cause those symptoms. Might not be the problem but...it's very inexpensive the check and could save lots of $$$ at the repair shop. I hope this helps and good luck!

A 2000 gm car would probably be due for a fuel pump failure, it is very common with the symptoms described. Those problems could also be caused by the crank position sensor,an ignitoin module, a loose ground wire, or a few others. Intermitant problems can be very hard to find, but if your mechanic is not living up to your expectations find a new one, unfortunately i can say for sure that there are quite a few poor ones out there

Serously, the absolutely, best way to find this type of problem is diagnose it while its happening, noone that I know can diagnose a no start on a car that starts thats not sarcastic see I specilaize in no start vehicles for many years. Someone has to make it happen, Does it happen more hot or cold? Rainy, or Dry? these are so very important take it to the dealer and tell them to keep it until it acts up then they will have the scan tool on it and when tring to start it they will "see what's missing" like crank sensor signal, cam sensor signal, fuel pressure, Primary ignition, plugged catalytic Converter,shorted 02 sensor, is the security system intermetantly being activated (this shuts off the fuel injectors)
You can change all the parts that say your neighbor did when their same car did the same thing and you will be wrong. Its so much cheaper and less troublesome to take it to the dealer and have it fixed once rather than hit or miss diagnostics which results in going to the dealer anyway.
If this information is helpful please give me a fixya rating and if there is anything I can do to further help please contact me. Sure there are items that I can recommend but........... as you read there are several areas that it can be which one do ya choose first?

2000 buick lesabre stall after starting or after running for 30 minutes


I have a 1996 Lesabre. I had a similar problem that slowly got worse. I brought it to two different mechanics that did diagnostic checks and could only "suggest" what to replace to fix the problem. Their problem was that it wouldnt stall out while they had the mv. After replacing a bunch of sensors and the fuel pump/ filter, I solved the problem by replacing the Crank Sensor. Its located behind the lower crank pulley on the 3.8 lt motor. Hope this helps!
