I have a scanner for the connector on my buick lesabre but it doesn't seem to communicate. is this model or year able to work with the scanner to access the codes??
In 1993, the computer systems were obd 1. which generally needed battery power to run scanner. 1996 up is obd2 and powers up scanner through data connector. not sure what kind of scanner you have. is it powering up ok and not communicating or cant get scanner to turn on?

Sorry to say, that is one of those GM cars that is difficult to retrieve trouble codes without special scanners. It was on some '94 and '95 GM luxury or upscale models (your LeSabre was one), where they put in the new diagnostic connector that became standard on all cars built after 1996- and called OBD-2 (for On Board Diagnostics, second generation). The problem is, your '95 model is typical of all early '90's cars and trucks equipped with the OBD-1 system. It only has 2 digit trouble codes, and there are not a lot of them, only about 2 dozen in total. The whole system is OBD-1, but the diagnostic connector is configured like an OBD-2 connector.
Some shops might have the scanners necessary to work on your car, some with high end scanners. Of course, GM dealerships would have the right testers, but they are outrageous in prices.
I would try to find someone who could get the codes for you. What you describe sounds to me a lot like a bad Mass Airflow Sensor, or MAF sensor. That is just a guess, though, and why I recommended you try to see if there are trouble codes. There should be at least one.
Flashing check engine light means don't drive it. It can damage things. Get a code scanner from auto parts store, rent it buy it etc. run the scanner to see what it says
Check the cigarette lighter fuse. This is what powers the DLC. If the fuse is good, check and see if the lighter works. If not, you have a bad wire. Code readers have to have power from the car. Most scanners have there own power and will read the computer, unless the data wire is bad or the computer is bad.
You must use a OBD 1.5 scanner. Even though the scanner is the same shape as the OBD II it is not electrically the same. You may have to take it to a shop with an older scan tool.
Hi, Check Battery and connections. Check for short in wiring. Also check computer codes you will need a code scanner for that. If you can not get it fixed go to a mechanic.
run an inline fuel guage in the fuel line with a clear line, look for bubbles, do this witha an inline spark detector, that should tell you wether its fuel or spark shut down, either of these will not give you a code, i have spent many a day on intermittents, sometimes you just have to go back to baasics
more than likely it's because the internal program is not interfacing with your vehicle. most scanners are programed with updated cam/cad where the smaller code readers only have OBD1 and 2 most vehicle computers after 2003 no longer use obd1 and 2...please rate the solution
