Hello everyone!! I just swapped engines on my 2000 CH with an engine that came off a 2002 Mack .. I am getting a fuel pump flash code on this (89).. The truck runs fine but it does not pass the emissions test in NJ.. Any of you know of a good Mack dealer in the NJ or Pa area that I could take this truck too?? Or any Mack pro in the area ?? I would greatly appreciate if anyone could help on this ... Would love to get this puppy running right again

Hello everyone!! I have a 2000 Ch with an E tech motor . I’m have an active code flashing 8 9 ...Anyone could tell me what might be the problem?? I have not driven the truck since so I’m not sure if any horsepower is lost. I do hear I minor skip in the engine when idling!! Thank you !!
