06 impala 3.5

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

don't replace the ecm. find out what blew the fuse. I'd look for power going through your ignition switch first.
