Hello all. I have searched and have done all the research on this cold start problem. Yesterday I did the ofv check and there was fuel coming out at idle. I already replaced #1 injector and tube(4.4 ohms). Now I installed the new ofv and rechecked. I still have fuel coming out. Now, is it possible so much fuel is going through the other return line backing up to the ofv? The truck runs great(when I do get it started). No codes and everything else is fine until you try and start it in the morning(30 degrees). I know this truck could use the other 5 injectors(214.000 miles). Any thoughts? Thank you in advance.
