2004 t7500 cabover with the 7.8L inline duramax (Isuzu 6HK1)
The truck will crank and crank but it won’t fire at all or even smoke. Ive tried to connect an obdII code reader to see if there are any codes and see if it was receiving a crank sensor reading etc but I can’t retrieve data. Communication error
So I am trying to located the engine ecm to check powers and grounds…..where is it!!??
I can’t seem to find the engine ecm. Does anyone know where it is?? Thanks for the help!!
