Group, Thank you for your input for a struggling newb. I had my truck running with a 5.3 from an 05 silverado. I have the following things that I have done and short story, it was running... I swapped the oil pan for a shorter pan by lifting the motor a few inches with my hoist. I set it back down and filled with fresh oil and it will turn over but will not crank.
5.3 L, 2005 truck injectors, stock tune, 54-454-11 cam, TBSS intake and throttle body with Xlink. Good ground to head and battery. Stock ECU, stock throttle and TAC module. New plugs, new cam, and crank sensor after crank issues started.
I have confirmed grounds are good. There are no codes, I confirmed spark and fuel, spark on every cylinder, fuel rails were pulled and injectors all sprayed fuel on cranking.
I enabled as many readouts as I could to try to diagnose my cranking issues. I am uploading the file here:

Like i said, it was running, now it will not even fire up. It sounds like it is trying but even with starter fluid I am not getting any firing cylinders.
