I have a 09 STS V8 AWD that has new batterys in the key fob and car. When I push the start button all power goes off....dash lights etc. after a period of time all come back on and we repeat with no start. Any thoughts?

Hi,

Let's see if we can get your STS going again:

Do the brake lights illuminate?

Do you get the push brake message if you try to start without the brake on?

Customer: replied 8 months ago.
on both
Expert:  Jared D replied 8 months ago.

Do you have a scan tool to check for engine codes/communication problems?

Customer: replied 8 months ago.
I do not. But had a scan run on it and found no code. Late one was a tech 2 and still found nothing
Expert:  Jared D replied 8 months ago.

And you had full communication with all modules using the Tech 2 right?

Customer: replied 8 months ago.
I asked the mech that ran the test and he said there was nothing he found that would be the problem. I will have to try someone else. Thank you

Was the vehicle running fine and all of the sudden it won't start or did it die on you at some point?
