Sorry if this post ended up somewhere else and was answered. Had trouble using site. Anyway.....
I have a 2002 7.3 excursion with about 95K. Engine light came on, I read the codes PO670/671 and began by changing the GPCM. Light went out but batteries were almost dead the following day. Charged again ran fine. Another few days later engine light came on again Codes this time were PO562/381. Code indicated possible cause of low voltage was batteries, had them checked ended up replacing both. No engine light, no new codes. Drove about 25 miles started feeling vibration eventually the engine died no start. Towed home, now starts but misses on acceleration. Have been told it's a good possibility a frayed wire in the glow plug circuit is the cause. Anyone agree or have thoughts on possible cause?

check the wiring to each glow plug with a ohm meter.

if you have a miss now, there is a good chance your uvch (under valve cover harnesses) is melted down due to a short and is affecting your injector wiring which goes through the same harnesses.

Great! Thanks for pointing out the video, I like the harness for testing will get one today. Probably be a couple of days before I can try this out.

OK...made the test pigtail found #1 GP high resistance. About to order a glow plug and new harness. Should I also include a new valve cover gasket or are they pretty robust and not prone to leaks?

The valve cover gaskets are pretty tuff IMO.
If it's not burnt and not leaking oil I would reuse it.
While I was under the valve cover I would replace the uvch.
I believe the international uvch cost 60-70% the ford part. If you have an international dealer around you can save some money.
