    Hot wire the fuel pump and listen for it, or hook up a pressure gauge to fuel rail and check for pressure. It's clear you have air and spark, just need fuel. Also check fuel pump fuse and relay. Good luck, great looking truck.

    My truck done the exact identical thing! Lol the motor had been sitting on an engine stand for a couple years before I bought it. I even started it off carbon cleaner like you, then checked fuel pressure and it was perfect. So pulled the fuel rails and Injectors and they were all kinds of corroded. Cleaned em good and bam we have lift off
