2000 buick lesabre limited stalling and have replaced a lot of parts...

Asked by Martha Oct 20, 2021 at 03:56 PM about the 2000 Buick LeSabre Limited Sedan FWD

Question type: Maintenance & Repair

I have a 2000 Buick LeSabre Limited
and have been having troubles getting
it to start and run. I have replaced the
fuel pump, fuel filter, fuel regulator, 02
sensor, cleaned the MAF sensor,
replaced 2 and 4 coil, changed out the
spark plugs, and  changed out the IAV.
I ran the the car without a problem and
the next day the car wouldn't run
unless I pulled the wiring on the MAF.
What else? No codes showing. The
last one was the 02 sensor and as I
say I've replaced it. I'm at a huge lose
of money. Can someone help me out
on here???

MAF sensors are sensitive to cleaners a special one has to be used . Disconnecting the MAF sensor and having the car run is one way to see if it is bad . If all that work was done by a mechanic then you need a technician or better mechanic . Throwing parts at a problem is rarely a good idea .
