Mackpro Posted August 10, 2018 Share Posted August 10, 2018 (edited) Double check battery cables as DEF ECM has its own small power wire and fuse right on top of the battery. See if you can read engine hours on the dash display under trip info. DEF level issue won't keep engine from starting. If you can't read engine hours, engine ECM is not powering up or communication issues Edited August 13, 2018 by Mackpro Quote Link to comment Share on other sites More sharing options...
mcratchet1 Posted August 13, 2018 Author Share Posted August 13, 2018 thanks, i check that cable and fuse all good. i pull engine hours it does not read just two dashes any idea where to go next or is this going to be dealer only problem Quote Link to comment Share on other sites More sharing options...
Mackpro Posted August 13, 2018 Share Posted August 13, 2018 Check engine ecm fuse in kick panel by clutch pedal. We have a test ecm we throw on a truck for problems like this. As theses trucks are getting older , we are starting to see engine ecm' s go out. The new ECM's are totally blank when they come in so it won't even start until programmed.

fjh Posted August 15, 2018 Share Posted August 15, 2018 (edited) Yup ! The Harness! this is another on going issue that seems to never got dealt with, Coolant push and oil push is quite common on these ! Oil or Coolant can be pushed up the wire from various failed or failing dollarstore sensors used on the engine and expansion tank right back to the ECU! However in your case the it looks as thou there was no coolant evidence or oil Did you clean it out? Edited August 15, 2018 by fjh Quote Link to comment Share on other sites More sharing options...
