edged-on

Thank you for the link. Update & Resolution: Looking through the electrical diagrams, the yellow sig return wire seemed to be the culprit, but I have no proof. After exhaustive connectivity checks, relay swapping, fuse verification testing, plug connector contact cleaning: It just fired up and purrs like a kitten. I believe the car just wanted a break; to be jacked up on the stands in the garage for a month or so.

I have a 2015 for Edge with a no-crank, no-start issue with the following codes: p0073, p0122, p0223, p0740, p1289 tracing wires from the temp sensor & throttle position sensor back to the ecu: wiring is good. These were the easiest to get to and test. Which wiring diagram suppliers do you recommend ordering from? thank you.
