Wish it were that simple, it won't even try to hold idle. just fires up , acts like its gonna start and conks out immediately. I know with the older Volvos there is a default mode for the ECU, and they do re=learn. This one won't even go to school. I suppose I will have to start trouble shooting for...

After I replaced the original battery with a new one , the car starts , runs for a second and conks out.

Before replacing the battery , I pulled it and re-charged it, and the car started up and ran fine, so I don't think there is an alarm or ECU issue.
Help?!!
