2004 lb7 No gauges no run

Hi everyone, new here. I have read dozens of posts with similar problems to mine but not the exact symptoms. My truck started as normal then died after 5 seconds, now have no instrument cluster at all, totally dead. truck cranks normal but no start. I have checked every fuse all good I checked all wires at ignition plug all have power, pulled the edu and nothing works. disconnected the batteries, checked them they are good. I'm out of ideas other then to hook up a scanner like a tech ll which I don't have. Any ideas ......

How goes it?

By now, you probably had your ride towed to someone with appropriate diagnostic equipment.

What have you learned?
