I need help brainstorming crank no start

Sorry, the Torque Pro gauge you made was intake manifold pressure, not intake air temperature. Can you please change your Torque app to read it (it's the PID right above the one that you selected). If it is OK then we will move on. Just need the PCM to actually see a temp there that makes sense.
Yes please no problem you are helping me 😁 let me get that
When you lined up the timing marks on the balancer, did you find both of them (as described in the factory intake manifold instructions that I linked)?

Les has you on the right track with scanning capability and compression testing.
Keep in mind that your distr cap carbon tracks, intake back fires and messy spark output confirms that you have an ignition problem as part of this issue.
Your plug fouling adds adds to the mystery. I don’t remember, when you pulled the fuel pump relay fuse did you try a starting fluid to see if the truck starts with the fuel system disabled? Be careful and go easy with this test given the timing problems. Have a fire extinguisher handy. I once had a rotor tab break and point in the wrong direction creating timing problems and got the same flaming back fires that you are getting. I had to sacrifice a piece of clothing to put the fire out.

i should be getting the compression tester by tommorrow see if I can sneak in the test (valentine's day lol)
I also want to recheck that distributer and make sure they didn't put the rotor in backwards if thats even possible lol when I got it i just removed the cap/cover to install never touched the rotor.

That adds additional mystery to your situation. On the one hand you see wonky spark results at the plug and see carbon tracks in the distr cap but it runs good if you start it without the fuel pump in the circuit. This implies that the fuel pump circuit is perturbing the ignition circuit. Watch spark at the plug end of the wires first with the fuel pump relay in and then again with the fuel pump relay removed. It doesn't matter if it starts for this test. Is there a difference?
