See if it starts on ether. If so then its definitely fuel related

Is your glow plug light staying on for no reason?

could be a bad wire in the harness or if you got a used ficm it was probably also junk

Dumb question did you hand prime the truck until the primer gets hard my truck lost prime one day and acted exactly like this till I hand primed it? I heard you deleted the under hood filter after typing this but sounds like a prime issue to me

this is easy. you have a u code and the truck won't start. I bet my paycheck that it's the edu circuit in the fuse box. I have the exact same truck

Not familiar with all duramax engines but don’t you need to pump prime it with the little hand pump on the engine? Or did you just not video that part.

Mr. Pickel :
Tuner? What does your fuel gauge say? My lb7 had a weird communication issue with my tuner and it would only start if the fuel gauge was on E with the light on

it’s air locked. the rails are full of air which causes rail pressure to only build about 220-400 psi. make sure you cycle the glow plugs like 5 times to make sure they stay off or unplug the glow plug control module and shoot ether into it and it will make the injectors fire which will release the air and let rail pressure build up. you almost have to do it everytime when doing a head gasket job and i did my own and it did the same thing. the cp3 running dry for the time you turned it over did not hurt it or blow the seals out. you have to run them dry for a long time to blow them out

When yours cranks its uneven almost sounds like a dead cylinder. Mine has a steady crank the whole way

How low is it on fuel, my brother’s lb7 pickup tube broke off at half a tank couldn’t figure out what was going on would still get fuel to the engine but low fuel pressure ended up just putting 5 gallons of diesel in the tank and truck fired right up, shortly after we did a sump on the tank, not sure if this is your issue tho
