I have a 2011 Buick LaCrosse Cxl 3.6 and it’s doing the same thing my dashboard light come up but wont start, can u tell me what u did or fix to get it started?
sept. 2020 i went to DR.'s appointment . 2 hrs later i opened the driver door to 2011 buick lacrosse and i heard a loud very fast machine gun sound under the hood . i got in and push the button and nothing ,no crank no start . it drove there real fine and been driving well before this . here are my tools i have ,BLUE DRIVER , POWERPROBE 3 , POWERPROBE "THE HOOK" , POWERPROBE ECT -2000 short finder, and computer safe test light which test grounds and positive power . my code was/is UO100 and PO23F ..... I DOWNLOADED MANY MANY 1000's of PAGES from MITCHELL 1 , AND ONLINE CHILTON MANUEL . I SPENT A YEAR AND A HALF TRYING ALL SORTS OF THINGS .I WISH I HAD YOUR KNOWLEDGE AND DIANOSTIC EQUIPMENT LOL . po23f states open condition in secondary fuel system . i also noticed the connection x108 has a lot of these suspect wires going thru it , sometimes my shifter indicator light on shift stays on ,sometimes my gas gauge works ,sometimes it dont , these things happen when i mess with X -108 CONNECTION . so check this out , when i connect battery ,the machine gun type noise is heard under the hood . it does for a few seconds then stops , few minutes later ,it does it again . when i unlock my door or trunk with my remote or by the key ,that machinegun sound starts up again . IT WILL BE 2 YEARS THIS SEPTEMBER THIS CAR HAS BEEN PARKED , I HAVE NEVER HAD SUCH A PROBLEM WITH A CAR EVER BEFORE . i know starter is good because i got it to turn over by using a jumper wire in fuse box . i wish i knew how to use the tools i have a lot better so i could fix this car . ALSO I CAN HEAR MY FUEL PUMP RUN FOR A SECOND OR TWO WHEN I FIRST TURN THE IGNITION ON . so my fuel pump and starter works . this video gave me the will to go out there and try again . any idea or tip i get from you is greatly appreciated . THANK YOU FOR YOUR SERVICE MY BROTHER !
My 2012 started clicking 2 days ago. Just got my new alternator and replacing tomorrow. Will update. Replaced my starter last year and it was doing nothing when I would try to crank it before I replaced it so if that happens that's the issue. Now I believe it's the alternator because the battery will still hold a charge when recharged. Fingers crossed.
there is an internal switch inside the transmission that goes bad. advised the shop and it up to them and the owner of the vehicle. Couldnt do more, just got called to fibs there issue
So your basically saying it’s the park neutral safety switch that’s messed up , sending info to ecm thinking it’s in gear? So what would happen to the black and orange wire if you were to direct it to positive and drive as daily ? I mean what could go wrong right ? 🤷♂️.
It's a safety problem, what if a child is inside and plays with the gear lever and starts the vehicle. There is a reason why the engineers put that system
Gracias x su service sr
Thank you very much. It is a safety feature.

My sister in law the 2011 buick lacrosse cxl and she haven't the same problem it won't turn on only clicks.wat can it be wrong
Alternator, starter, and/or battery
My 2012 started clicking 2 days ago. Just got my new alternator and replacing tomorrow. Will update. Replaced my starter last year and it was doing nothing when I would try to crank it before I replaced it so if that happens that's the issue. Now I believe it's the alternator because the battery will still hold a charge when recharged. Fingers crossed.
HOW MUCH DOES THAT AWESOME SCANNER COST BROTHER ?
i got it for 1700 years back now you can see them for 1200. good scanner
What was the problem for the Buick not to start
@@ivesstreet4916 i had pulled the fuse box out and had a loose connection underneath , so dont ever pull out the box lol !!!.
hey Juan I am having the same problem with my car, same car by the way,....just for FYI what did you have to do or replace that fixed the problem?
there is an internal switch inside the transmission that goes bad. advised the shop and it up to them and the owner of the vehicle. Couldnt do more, just got called to fibs there issue
That’s why the dealer couldn’t figure it out
What’s was the problem
will not crank. this isnt a how to channel just fyi
Where are you located?
fort wayne Indiana
Do you travel to Michigan
So your basically saying it’s the park neutral safety switch that’s messed up , sending info to ecm thinking it’s in gear?
So what would happen to the black and orange wire if you were to direct it to positive and drive as daily ? I mean what could go wrong right ? 🤷♂️.
