yellow and green wires reading 62.5 ohms with battery disconnected. The fuel relay for feed pump is not turning on, relay and fuse are good. I would like to test wiring going to the ECM plugs, but the numbers on plugs 1 and 61 does not make since to me, went through volume 1 and volume 2 of book, it shows most of the smaller plugs and one large round plug with letters, but not the plugs for ECM. Anyone out their work on these?
Thanks for Reply's
I'm thinking it's missing some grounds, there is a small black wire the bolts to middle of engine block on left side, EcM side that wire is cut and no clue where it goes, should there be a ground wire going to ECM housing?
La comunicación del can bus esta defectuosa, revisa cables o pines. Revisa el cable amarillo y verde que esta trenzado y pasa por toda la maquina la resistencia debe medir 60.ohm

The can bus communication is faulty, check cables or pins. Check the yellow and green cable that is twisted and goes through the whole machine, the resistance should measure 60.ohm
The guys put the ECM back in truck it has code 2000-12
maybe the ECM is ok
Was hoping to find someone who tests these before chasing the problem, to many people have been working on this thing.
the engine has been out 2 times for repairs.
