Drove my 2014 Prius to the repair shop, it sat there for ten days then was driven to another location at the shop. Body work was completed and now it wont start. Tried jumping didn't work, so installed a new 12v battery: all dash lights came on and even the ready light for a few minutes but then ready light turned off and we couldn't get it started again. Unplugged the 12v battery waited 10 minutes and re connected the battery- still no ready light. Any ideas please?
