You may also have the Pass-II key alarm system installed. To tell, the ignition key will have a black sensor on both sides. If this is the case, 1 of 2 things is happening. 1) The key needs replacing with a similar style key only from the dealer. 2) The coils in the ignition that hit the key sensors are in need of replacing. See dealer for more info.

The crankshaft position sensor may have a fraied wire inside of the pickup coil in the sensor. This can sometimes cause an occasional problem. There is also a computer ground that will sometimes go out on those.

    Yes there is. When you try to start it do you see any security or theft lights?

Sometimes my 1995 buick lesabre wont start then later it starts


These cars are notorious for failing antitheft systems. When this happens, the car temporarily turns off the starter as a theft prevention measure. It normally resets in about ten minutes, and warns you with a light on your dash that reads SECURITY or ANTITHEFT. This link explains the problem, and how to fix it.

Were is the starter located on 1998 buick lesabre


Before changing out the starter, be sure that the SECURITY light is not illuminated on the dash. The anti theft security on these GM vehicles can actually disable the starter if it is starting to fail. I see people change starters way too often when its not the real problem. If that light is on, check this link http://vatspasslockpasskeysecurityhelp.yolasite.com/ If not, just repost this problem for more help

My 1999 buick lesabre has a dinging noise when a brake sensor


This means your master cylender is low on brake fluid , top it off with brake fluid and that should solve your problem . You should find out where the brak fluid is going .

1998 buick the lights on climate theclimat go crazy and car dies


I would say your best bet is to take it to the dealer and pay the $30 to have them run a computer check on it.  Tell them you want a printout.  They will probably be a little reluctant to give you a printout, but hey...if you are paying for them to tell you the problem, you should have the proof.  Not all but some dealerships will tell you it is like a $400 part deep inside the dash that you can get to without special tools.  When in all reality, it is as simple as a vacuum hose.  That is why I work on them myself!
