when you say "power junction point" do you mean the engine fuse block? I am having the same problem as Pedro and I have narrowed it down to the fuse block. The E wire ties to the wire that goes to blue 75 on the ecm harness, a pink wire comes from IGN 0 , from the dash fuse block, and plugs in next to them , no fuse no nothing on top side of fuse block. I assume the buss wires transfer power from one to the other, but nothing in my case. Is this what i need to replace? thanks
