Just had my injectors replaced in my 01 durmax, I had it done at the dealership. The problem is now that it cranks over really hard, like it dont want to start, and in the morning when starting it cold the glow plugs only stay on for a sec then when u finally get it started it sounds very uneven, kinda like someone is pressing on my gas. I took it back to the shop and they cant figure it out. anyone have an idea's?? I am very frustrated with this and them, I only have 78000 miles on it... thanks...

 

try taking the duramax out and put a cr cummins in front of the allison that should fix it

 

is it throwing any codes?
