I'm new to this forum thing and in desperate need of some advice. I have a 04 GMC Sierra 2500 HD 6.6L Duramax LB7 that I replaced injectors, return line bolts, fuel filter & primer over last few weeks. I finally got it to start and it has good fuel flow but I have white smoke with misfire? First time I replaced injectors (December 2014) I had fuel spitting out of exhaust and replaced another bad injector. No codes. My brain is just overwhelmed and I'm not sure what to do next? Im ready to find a good diesel technician in Delaware or blow the truck up so Any help will be greatly appreciated.
