Question about 2000 Buick LeSabre
Hey Gary,Buicks have many sensors and are very known to have problems with them,the problem is which one is bad.The best and cheapest way to fix is to have the Buick dealer repair,doing it yourself can be costly cause you will replace good sensors trying to figure out what is wrong,these vehicles are hard to trouble shoot.I called once for a friend,Buick quoted a price of 75.00 to trouble shoot,he didn't do it,evenaully he paid someone over 600.00 and it never got fixed,sold it to a junk yard.

i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em

Make sure and check your ignitioin fuse if its out the car will start it just wont stay running verry long sometimes in most cases will turn over but not start

SOURCE: will start then dies
On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?
