mackattack3 Posted February 1, 2013 Share Posted February 1, 2013 I have 96 CH613 E7 427. I am getting codes 6 2 and 6 3. The chart says 6 2 is turbocharger speed. 6 3 is J1708/J1587 link. it will crank and then die like its not getting fuel, wont restart. Have had trouble with connection on fuel actuator before so I went there first. I can unplug connector and replug, it will crank and then die. I realize its probably a bad connection somewhere, and idea where I should start.

mackattack3 Posted February 3, 2013 Author Share Posted February 3, 2013 Any ideas, cant find anything obvious. Its an E7. Normally the code gives you good idea where to start, but 6 3 is too vague.
