Hello! Throwing a Hail Mary out here, hoping someone can catch it!
I hopped in my 2011 Edge (3.5L) the other day, hit the starter button, heard the engine engage for a split second, only to then die while the starter continued to spin. Tried a few more times with no engine response at all; only the whirring starter. Fuel pump was the first thing that came to mind, but I could hear it whirring when I powered the vehicle on. My mind then turned to the ignition...
I pulled the fuel pump fuse, popped the connector off of one of the coil packs and put a multimeter on it. I hit the starter, and it never budged past a few hundred millivolts. I pulled the coil out and put the multimeter on that... 0.9 ohms across the two terminals, but no reading whatsoever from either terminal to the post; "open loop", according to my meter.
So now I'm thinking wiring harness, or perhaps PCM. Harness looked fine upon visual inspection, so I pulled another coil and tested it. Same thing. Pulled the third one from the front and got exactly the same result. Dreading what came next, I went ahead and pulled the intake manifold so I could get to the remaining 3. All tested the same. There are no visual signs of destruction on any of the coils, but all 6 of them give me an open loop reading from either terminal to the post. Am I crazy/doing something wrong, or can a massive coil driver failure in the PCM ruin all 6 of them in one fell swoop? I had no issues whatsoever before; no problems starting, no hesitation, nothing. It really just died very suddenly.
I don't have a code tester, but I could grab one, I suppose. Question is, how would I test this now that I've taken half the car apart just to get to the coils (thanks, Ford!)? I've checked around town, and apparently, no one in Washington State except a dealer will touch these things, and I know I'll get screwed if I go that route. What now? Ship it off to one of those PCM repair places and hope it's actually the problem?
Thanks in advance!
