Question about Buick LeSabre
Fisrt thing is having repeated fuel pump failures is real common. Several things can cause this. Chevy trucks recommend replacing the fuel pump harness also when replacing the pump or this can happen. Weak old wires can cause a voltage issue causing the pump to burn up. Also alot of fuel tanks have a coating that can fall apart and be abrasive to the pump causing failure. You can search,,, Repeat fuel pump failures.. and find this info easily. Chrysler has issues for the 98 99 years for their Cherakee fuel tanks requiring replacing the tank also with a new pump.
Hope this info enlightens you.

I know you don`t want questions,but I want no answers,this is for you to ask yourself,and the techs.Has anyone bench checked these fuel pumps to see that they are actually bad?Is there voltage at the pump,when key is turned on?Are all these pumps been the same brand?purchased at the same place?Was the tank inspected for a contaminate,or trash in the tank?If all the pumps are correct applications ,for the car,and are actually testing bad on the bench,all of them,then I would change the fuel pump relay,and install a new fuel pump harness all the way back to the pump.Have the alternator checked for a c voltage out put.A alternator actually produces a c voltage,and has a rectifier ,that has diodes to turn the a c voltage into d c voltage before the out put.If there is a diode that has gone out,in the alternator,it will produce some a c voltage,not much,but enough to cause a small motor to burn out in a short time.If gone undetected,if the alternator diode gets worse,or starts allowing voltage to go the other way for a while,it while finally destroy the rectifier,and produce more a c voltage,and everything will be effected.The starter for one,because the a c voltage will finally charge the battery with the a c voltage,I have never seen a battery fully charged with ac voltage,and I don` t think I will,cause it would most likely blow up before that.Maybe this was helpful,and maybe not,but there it is,take it or leave it.Just trying to help out if I can.
