My truck won't start and nothing works. Power windows, turn signals, radio, anything at all. I just took my tuner off and this happened. Tried to reinstall it but won't take and an error came up. I am out of ideas.

Do the headlights come on? Horn honk? If so I've heard that unhooking both batteries for 30 minutes might help. Hope it gets up and running for you soon.

From looking at my fuse layout on the cover it doesn't even show I have a BCM fuse and I also checked the fuse box in the truck.

Mine has donr the same thing TWICE. Both times it was just a loose fuse under the hood.

It may be but I have been over the fuse layout over and over and it is not labeled. And I checked all my fuses to see if the are completing a curcuit and everyone was good. But people keep telling me about this BCM fuse but according to the layout I don't have one which seems odd.
