When you turn the key the only thing that comes on is the check engine light?

There is power to ignition wires wht/blk, wht/red and wht/grn.
There is no power at the ignition wires (wht/blue and wht/yellow) although when testing the white with yellow wire,
I believe that it receives or sends a 5-volt signal to or from the BCM (pass lock) then the white/blue would send 12v to run/crank?
Hence why I think it is the BCM.
Am I wrong?

I got a new BCM, door chimes started working as soon as the battery was connected.

Started the pass lock relearn. Turn the key to start, wait for the pass lock to stop, turn the key to off. Repeat,
I did 3 of these 3 consecutive times before I didn't get to turn the key off after the pass lock light turned off for about 1 minute. On the 4th time I turned the key to start and it did. Yeah.
But I thought you need to do these a complete 4 times and on the 5th time it would start?
So, when it started on the 4th time I panicked and shut it off. Only to turn the key to start again and the truck started but I noticed. That the pass lock turned off seconds after starting it.

I have no dash tachometer, display at the bottom, gauges, turn signals on dash (they work on the outside).
Also, 2 codes now (p0017 and p0315).
I cleared them and they are right. Back?

Thank you for the outstanding guidance.
And any more help will be very appreciated.
