New here to the forum. I'm a member of another duramax community and I'm coming here hoping to contribute my knowledge and have better advice. It kinda gets old when you have a problem and the replies you get are you need a lift pump or your injectors are bad no matter how new they are and you've never needed a lift pump before. I guess these duramaxs just decide they need one out of the blue and won't run right anymore without one lol
