Default 2007 Suburban Cranks, No Start even after many new parts. Help

Hi, Yall. Need Help with recently purchased non running 2007 Suburban. So, New battery, spark plugs, spark plug wires, ignition coils. There is solid spark when cranking the engine( at least at one cylinder ). Then... New fuel pump, injectors cleaned, fuel pressure checked (a little over 50psi while cranking). Fuel pump relay is good, injectors fuse is good. Doesn't even start with starting fluid after all. Any ideas? TIA

Can you give a little history of the vehicle?

Welcome to the forum.
Need to check compression on all 8 cylinders. The GMT900 had some severe issues with the AFM causing failed lifters. If that's the case, it's an expensive repair and I hope you got a really good deal on this truck.
