i have a 2008 duramax that i have been working on for 20 hours trying to figure it out. the problem is that numbers 4 7 8 injectors arnt firing i have replaced thows injectors and still no luck i traced and checked all the wiring and found that it tests all good i replaced the ecm and had it reflashed still no love on thows injectors i tested the new injectors and they work on another truck also programed the injector flow rates into the computer no luck the injectors still dont fire i am about ready to have a bomb fire with this truck and roast marsh mellows over it but before that happens does some one have any ideas on what else might cause thows injectors not to fire and i am getting fuel to the injectors as well and the injectors that i installed are brand new right from bosh not remanufactured any help please lol or the next post might be a pic of me roasting marsh mellows lol thanks for any help :argh::s:

roasting? :scare2: by chance did you do a drag test on the pins in the wiring and make sure they are making good contact? or a voltage drop readings at the injectors? I know this is an old post but no one helped and I was curious. :humm:
