Cxu613. Just noticed yesterday I went to start the truck and it took two attempts to start. First time it’s done that I have 526035 miles on it . Once started it drives fine in fact iam hauling 45,000lbs to Wyoming and it’s done just great now iam parked at truck stop and I let it idle for a hour and turned it off . I went to start it and it did it again hard to start. Since the beginning if I tap the key it would fire right up now it seems in the last two days it’s struggling. I called the dealer and right off the bat he says oh you sound like you need 6 injectors . Is there anything I can do to troubleshoot this instead of just throwing down 6 grand and hoping the dealer was right ??
