Can "JUSTANSWER.COM" Fix Your Car? (Part 1: Nissan Titan NO-COMM for a YEAR!?)

Oh boy, here we go again!
This 2011 Nissan Titan V8 lost communication with the ECM a year ago, and has been a BEACHED WHALE since.
The owner obtained a replacement used ECM and had a shop program it.
Truck actually started and ran, but was in LIMP MODE with no throttle control!
Parts Cannon got fired up:
APP sensor, Throttle Body, Fuse Box... now the truck is back to a NO-START, NO-COMM!
In desperation, owner went to JUSTANSWER.COM and they suggested that he CUT ALL of the 5V reference wires at the ECM to try to get it back online. WOW...
Obviously that was a BIG FAIL...now the truck is completely DISABLED, and has a BUTCHERED WIRING HARNESS!!!
Owner finally towed it to PHAD 3 hours out-of-state. Last Resort.
He says that he already spent way too much TIME and MONEY on this truck, and wants a DISCOUNT!!
Let's open up this CAN OF WORMS and see if we can get this truck back on the road...
