Just ask the shop if they can do a CASE relearn. You would have to drive it there and it has to be running. Not having this done would not prevent it from running.

Do you or do you have a friend that has a scanner to read codes? A crank no start should have a live or history code that could point you in the right direction. I'm betting that a CASE relearn would fix the problem.
Most shops (in my area) charge $100 or so to do a relearn. You could also look into a mobile mechanic, that should have an advance enough scanner to do the relearn. Or at least get the codes for you.

Sorry but no since it MUST be running and able to go to wide open throttle to do the relearn.
To me, this sounds more like a fuelling problem.
@colecole2020 , try starting the engine with starting fluid. If it starts, it's a fuel problem.

Nothing really except the CEL and code for it. If it's not giving a code for it, you don't really need it.
I would suggest going back to basics, with amount of work that you have to, checking the "no start conditions" which means "fuel, spark, air". Does anything happen when you provide "quick start" spray? If not, check for spark. Further, again with your work around timing, you should check compression on a couple of cylinders to confirm "mechanical integrity". Go from the results.

Was the truck actually running before you replaced all these parts?
As budwich said, go back to basics. When you turn the key to Run, do you hear the fuel pump prime up for about 2 seconds? You might need to have someone back by the fuel tank to hear it. If you don't hear that, the the most likely suspects are the fuel pump itself or the fuel pump relay. Could also be the ignition switch or the wiring to the fuel pump. If the truck was running before you replaced all these parts, then start looking at what you changed out. It's always possible to have parts be bad off the shelf. If it was *not* running, then you may have missed the actual cause.
If the fuel pump is running, make sure you have proper fuel pressure. If you do, then check for spark.
If the squirt of starter fluid budwich suggests above gets your truck going for a few seconds, then you have spark. Those two things should get your truck running, unless the fuel is not being delivered to the injectors. A failure at that level should be throwing a code.
Let's start there and see if we can narrow down the problem.
Good Luck!

Yeah, just to not confuse between the two threads, I'm closing this one. She did ask if it might need a CASE relearn to which I provided and answer.
