1997 Buick LeSabre will turn over but not start


Obviously can be one of a very large number of problems. If there are no trouble codes (DTCs), still could be a possible fuel delivery system (fuel pump, filter, regulator, throttle body) or ignition problem. I would start by checking the fuel pressure carefully - too high or low will cause this. Also the coil pack can fail without a trouble code - check for spark at a plug.

The ABS light and Traction Control Off Light just came on. What does this mean?


It means that the ABS has set a Diagnostic Trouble Code and Turned the TC off!! The TC is directly associated with the ABS. You'll need to take it to a Dealer or Qualified Automotive Service Center!

I have an 88 buick LeSabre/ vin "C"/ 3.8 with a trouble code 26. It only comes on going up hill


Hi! I have enclosed 3 trouble trees for you. The code being stored is a quad driver error. Quad(which means 4)drivers control up to 4 things. They are located in the engine control module. They provide ground for the items that they control. This could mean a component that the driver controls could be bad or the computer itself. Hope this helps you!deb334a.gif911608a.gif925db0e.gif

1997 buick lesabre, engine light stays on


The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.

FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.

Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!
