My 06, impala 3.5 just died going down the road the key does nothing the dash lights don't come on can't roll up the window. Scan tool that I plug into UBD2 says linking error. Under the hood I found a blown ECM 10 amp fuse replaced it and still nothing. I'm thinking maybe my ECM needs replaced but of course I want to confirm before I spend the money with someone smarter than me. Thanks for what ever help you can give
