Is your DEF tank still installed and wired in? Might be your DEF pump still pumping. Unplug the big bale connector on the frame near the back of the DEF tank.

Thank you--yeah that was it ! I killed the power and that solved that problem.
So now I'm finished with the truck, I took it for a ride and it runs and it sounds awesome! I'm really happy. I only have afew little details: the truck keeps asking to service trailer break system, also to change the fuel filter and my back up camera doesn't work anymore but I'll be working with the guy who did the tune hoping to taking care of those problems soon. So far the only things left to do is take the urea box off and put the heat shield on the turbo.
Once again, I want to say thank you to your guys for your help! It is greatly appreciated.

Take your bleeder screw loose at the factory fuel filter and turn the key on until you have fuel. Then crank until it starts.

Thank you that fixed the problem. Even tho I notice the sound of the fass is not to loud but it kinda sound like its about to give up. Little rough sounding

So after a few days the truck still running good, I juts still dealing with the service trailer break system message and my back up camera that doesn't work yet and also my fass besides being loud it sounds like shit.
Anyway today I took the urea box and it's pretty simple just a matter of taking 4 bolts out and a couple houses off as well. I also installed my probe for the CTS that was probably one of the simple things to do!
No I'm wondering what else can I do to the truck? Also thinking to get rid of the fass and go with a dog I hear the are much quieter.

Kennedy pumps are completely silent, if I can make a recommendation. If you get the harness with them, there is an oil pressure switch that turns the pumps on with the engine on, the pumps will prime at key on engine off for a few seconds like a gasser does, then shut off, and there is a button on the controller you mount to the firewall that gives you manual operation for things like priming fuel filters. It's a really slick setup. I have Kennedy twin pumps on both of my trucks.

Oh I'll be interested to install one of those in my truck! This fass POS
It just sounds terrible and after a week since I installed I'm tired of it
The only reason I went with a fass was because that's what I had in my lb7 and
It didn't sound that bad.

Have you called fass and talked to them? I've yet to have one that I thought was abnormally noisey.
