Ford Mustang 2018 Ecoboost 2.3L 71000 miles
Hi everyone! I recently updated the sync 1 module in my 2018 ecoboost to sync 3, and my car suddenly got into a no crank no start situation. There analog gauge is not showing anything, and when I press the start button there is a small click sound but nothing else. Sync module can still start with engine off. I charged the battery in full but still got the same issue.
