I'm back up and running...and I have a spare ECM to boot. I found that the 20A fuse for ASD power was blown. I called myself checking this fuse multiple times but apparently it was not discernable to the eye...should have put an instrument on it like I did everything else. I also found a chafed wire in the harness where it goes over the oil dipstick bracket which could possibly be the culprit. Repaired that as well. Thanks for the help
BTW... another happy wranglerfix customer. Jeep runs great on the replacement ECM. Now that I know I don't need a new ECM, i'm still running the old one and will put the wranglerfix ECM on the shelf as a spare.
