Why is my truck completely dead?
A completely dead truck could be caused by a bad battery, faulty alternator, broken starter, blown fuse, or even a bad connection at the battery terminals. A diagnostic scan can confirm the root cause and determine whether a simple part swap or deeper repair is needed.
Why would a truck just shut off?
Common causes include electrical system failure, fuel delivery issues, ECM problems, or a failing alternator. If the engine suddenly shuts down during operation, it’s critical to inspect fuel pressure, battery charge, and fault codes immediately to avoid further damage.
