Any one can help please? I purchase a 2021 buick envision preferred with 4k miles salvage title from copart. It has a right front end hit and airbags deployed in the SUV. The SUV does not have any engine or transmission damage but it will not start. I purchased another one for use parts with 8k miles, front end on the left hand side and roll over damage. All airbag deployed , no engine or frame damage but this one does not start either.

Does anyone has any idea how I could get these two SUV start. It seems that there is something on these SUVs that will not allow them to start after they crashed. Also the batteries on both of these SUV look ok but when taken to autozone to recharge they batteries are completely dead.
The other weird thing, is that the radio panel lights up and played on both SUV, and yesterday, purchased a new battery to test. I had disconnected the airbag crash sensor on the front of the SUV and the connector that connect to the battery terminal when I was swapping the battery for testing, when I connect the new battery the radio did not display but it was playing, I reconnected the sensors and could not get the radio screen to display again on either SUV. This was weird.

The main issue I am concern with is that I cannot get either of the car to start so I can place it in neutral to get them on the tow dolly. PLEASE ANY HELP will do. I called the dealer service center and they are reluctant to help. I am sure whatever is happening to one is happening to both.

What does "will not start" mean? Do they crank and not fire or do they not crank at all?
When I connect the battery terminal, all the lights turned on. When I press the brake and the start button, the lights went off the start button and dash display as if the car shuts off. When I press the brake and start again the lights came on, no crank.

Where on the 2021 is the inertia switch, it does not look like this has one. I could not find any reference of this switch online or from the GM parts store.
Don't know the answer to that question. It is possible it does not have one, but pretty much every modern vehicle has some sort of emergency fuel shut off in the event of an accident.
