Happy 2024 everyone!

This truck due has a intermittent & worsening issue that would cause no crank no start & sometimes would cause the all power to go off when the ignition key's turned.

I just replaced the ignition switch with a Dorman 924-715. Fits fine. But it did not resolve the starting issue or the no power issue. Matter of fact, it now consistantly have no power except the key chimes. 

What am I missing?

Thanks in advance for any/all helps!
