I have a no crank no start situation in my 07 Yukon 5.3 l. A bi-directional scanner is unable to communicate with it. There is no power going to fuse #56 ECM-IGN. Don't have a clue where to begin figuring out the cause.

Whoa... that's a lot of back story...I think you should keep everything in your first thread -> https://www.tahoeyukonforum.com/threads/replaced-engine-now-no-crank-no-start.149652/
That way people can see the whole backlog.

Their issue was the RUN/CRANK relay going bad. (which powers your ECM-IGN fuse among other modules you have codes for)
