2010 Taurus sho no HS can bus

This car has been in a small front end collision that broke some wires and stretched others. The motor blew because last owner tried to super glue map sensor hookup and plugged it. Leaned out and melted piston. Put a junkyard engine in. Ran fine for months then had weird shifting and wrench light on dash. Found Ms can bus system working but hs can bus bad. Can't scan. Dlc has good power, ground, resistance (60) ohm each leg of can bus. Voltages at dlc good for low usage (2.3v)
Only a few modules on can-bus high. Transmission connector was broken in collision but still connects. I have tried to unplug the abs, trans control module, I replaced the PCM , unplugged apim under information center behind dash. Unplugged most of smart junction box. Not sure if I'm unplugging too many things for it to communicate or something is wrong deep down 

There is also oily leakage by driver throttle that was at connector near by. The blend door also clicks non stop when the car is started

Update: car has communication when running but not on accessory power. Have power at run/start relay. Starting to think it's a smart junction box (sjb) problem

Sorry to see you haven't gotten any replies on this one.
I've been kind of upside down at work lately and haven't really had forum time.
There's no comm to any high speed module KOEO, but all modules are fine running?
Can you post the diagram for the high speed network that you are using?

Everything seems to power up fine with the first push of start button but no communication. As soon as it starts then it instantly establishes communication
