Actually Crane Hill area (lol). Funny, I mentioned that level (while cranking) of test to him this morning to see if we could detect a difference between the 3 wires when cranking. The coil wires exiting the ecm appear to be on the same connector as the 12 volt power to the ecm, thus, the tests must be performed with connector attached to the ecm. I'll try to construct a jumper. Continued thanks for your help my friend.
