Well the mechanics can’t figure it out .. there’s no power going to or from the ecu.. they’ve checked the batteries, fuses, relays, and look for broken wires checked each harness going to the ecu and didn’t find anything there.. so there’s another guy who’s going to come look at it this afternoon and see what he can find.. so idk what to do guys...
Find a better mechanic. It really shouldn't be that hard to figure that out.
did you pull harness and verified you do not have power to ECM? Look under hood at the fuse box make sure thats good also you will have another fuse box at wither batteries or up on firewall for ECM power make sure all thats good....
They pulled each harness and looked at the pins and for broken wires...they checked the fuses under the hood and checked the fuses inside the cab and found it all to be good..
What about the ones in battery box? You will have a main panel for Engine either on battery or on fire wall.. Not the box one that has the relay and fuses for nox sensors location one...
I see only two fuses and one relay inside the battery box.. they check out ok..
steps for diagnosing ecm power issues...
1- go to battery box and verify connection and fuses/breakers.
2-follow wires to Power distribution box
3-test wires at distribution box/maxi fuses
4-follow wires to ecm itself.
Its literally that easy, they dont go anywhere else. If all else fails just run the dam power yourself and get it somewhere with a mechanic who can fix it...
