Hey Brian O’Malley,
I had a similar situation to what you are experiencing on a 2014 MacBook Air. But first I have a few questions.
What was your motive to replace the screen and keyboard. Did your computer experience any sort of liquid damage?
Also, once your computer is booted up does the power button work at all?
Does your computer show any other signs of needing an SMC reset other than the power key not working? See Apple’s list of signs at the bottom of this article: https://support.apple.com/en-us/HT201295
-The MacBook Air I mentioned earlier had experienced water damage. It had the very same problems that you mention where I order to get it to boot I would have to first disconnect the battery then reconnect it then connect the MagSafe cord. At this point the computer would automatically boot up by itself.

My MacBook Air also showed signs indicative of needing an SMC reset but since the power button was broken on my computer I could not execute one. I even replaced the entire keyboard but (which on my model contains the power button) but it did not fix the power button.
It was many months later that I found out that the Trackpad ribbon cable is also responsible for carrying current for parts of the keyboard including the power button. By replacing this cable I was able to fix my power key.
It occurred to me that maybe you need to make sure that your trackpad cable is securely back in place after reassembling you computer.
If that doesn’t work, maybe its worth considering replacing the trackpad cable to see if that helps.
Here is iFixit’s link to your trackpad. (Make sure to read the product description to make sure you purchase the one that includes the cable as well since that’s what we want to replace.)

I hope this info helps and if it does make sure to rate my Answer! :)
