PLEASE HELP CUMMINS ISX 15 2011

Hello drivers and mechanics. Whenever i find the soultion i’m posting here and now seriously i will need your help. I have this volvo with cummins isx 15 500hp vehicle is 2011.
I took it to the shop for driveline vibration and clunk , but all of a sudden when the mechanic move the truck to put in the garage the truck would nor start. 3 and a half weeks my truck is in the garage, and this guys pulls everything they took out the cover on the head, remove all the house, removed waste gate, rebuild the head of the fuel pump, replace fuel filter. They said the turbo is good. I know they are not playing me cause this guys work on my truck in the past 6 years. Engine starts then right away dies. He said might be the pump it self which he said i was supposed to check when the head was off, but he will reopen it tommorow and see. what do you guys think, what can cause this issue ? literally he said i shut of the truck and truck never started again. Please help

 

can’t say no on this. cause i figure out they bs me over the phone everytime i called they say someone is working, and i went str8 there to check and no one was working. I will tow my truck to another shop

 

okay enden up turbo is shot. New turbo $7000 sucks.

 

EGR and def are bypassed. I don’t think i add coolant beside when i had an some coolant hose leak, but since egr is bypassed, is it possible that can still cause issues ?

thank you

 

I wasn’t sure either, but thanks for ur time. Have a good day hopefully this will be helpfull to someone else.
