Thanks.
Took the fuse box out and took it apart. Key relay looks perfect certainly not welded, actually has some continuity issues ( in my feeble diagnostic mind) in the printed circuit board from the key relay to the spade terminals that the harness plugs into. One side is "open".
Ordered a new fuse box and hopefully that will fix that, then I will move on to the other codes if still present. Unit is dead in the water until I can at least start it back up.
