Truck will not come on, no lights no sounds. Battery , starter and alt fine. What would be the most likely cause of this?

Sounds like a wireing nightmare? I would check any ground wires then trace the hot wires. Checked all the fuses?

Check efi fuse, maybe even test the starter relay. see if you can pull a code on it. Test the circuit opening relay. If that doesn't function, the gas pump wont turn on giving the engine the gas it needs to start.
