These are the codes I now have after trying to jump my other car. Before "this" my car ran great.
Now it will not even turn over.
Ignition switch???

 

It could be, have you contacted hellshotrod?

 

Most of those B codes say you fried a bunch of hot wires, the other ones say the airbags are not getting power. My guess is you need to do major surgery, possible replacement of the fuse box.
The U codes mean none of the modules is getting power.

Start by checking for 12 volts on the LARGE red wire, the one that comes directly from the battery. The disassemble the fuse box looking for fried wires and connections.

 

I actually was thinking the same thing. Yesterday I went to pick n pull and got the fuse box, the 2 module things in front of the fuse box and was trying for the ignition but couldn't get that out.I also found a relay behind the fuse panel on the inside of the car.
So as I am checking out the fuse box under the hood I undo the clamps holding the ECU box and when I took the gray one-off it has this burnt oil looking stuff in it?? My car does not leak oil or anything for that matter.
If I did it right I did send him a message but no response as of yet.

 

My guess is the oily stuff is dielectric grease. I would clean it off and apply some new (known) dielectric grease.
First to check the under hood fuse box.

 

I am in Modesto

 

This is update on my 06 LT.
I am not exactly sure when or how I came to actually having it running again. Because I did not have the fuse box which I replaced tightened all the way down. Finally seen a video or post that stated when tightening fuse box back down when it sounds like ur going to break it, still have about 8 more turns before actually tightened. Then it started right up.
These are things I did.
Replaced fuse box (under hood).
New ECM
New fuses.
Stressed, flustered and stressed some more.
But on the road again.

 

Thanks for the follow up! Glad you got it fixed, enjoy the ride!!
