Default 6.0 will not start

Hey guys! New member here. Have a problem with my ls swapped 96 Silverado. About a month ago I took my already 6.0 swapped truck and swapped to a 4l80, and tbss I take and injectors with a dbc 92mm throttle body. Truck was running fantastic and drove out of the shop and down the road to my house. Fast forward to 2 weeks ago I’m getting ready to go to school. Last thing on my list is fire the truck up. Ran flawlessly so let it charge the battery, shut it down and off to school I went. The following Friday I come home and go to start the truck to move if. Truck starts, ran like trash for a few minutes spitting some black smoke then dies. Never to even try to fire again. I’ve changed the crank sensor, I have 58psi of fuel pressure, I have spark according to my inline spark tester and my injectors are firing according to my noid light. No codes either. I’m out of ideas on this thing and was wondering if anyone has any insight or suggestions. Thanks guys!

Can you confirm that you have spark? I would double check all of your grounds as that's fairly common too. Maybe make sure your injectors are spraying fuel as well.

double checked all grounds and my inline spark tester is lighting up. Messed with it more today and I’m getting a heavy fuel smell when cranking like it’s flooded. Gonna grab a new set of plugs and try again
