That was back in Oct-Nov. The alt was working but not keeping the batts (brand new in Oct) fully charged. I switched to a CS144 alt and now no more charging problems. I only have a small batt charger, no quick start charger here, though I did jump start off other vehicles several times before resolving the issues. I took an almost new GR starter off an 83 6.2 I have and put it on my 94, what a difference in cranking speed. I then rebuilt the old starter, even though it was still sort of working, and put it on the 6.2. Cured the slow crank issue on the 94 and the rebuilt starter is now working good on the 6.2.
The PMD issue was about early Jan. It died out on the freeway (had already had multiple throttle blips and one race incident) so I had to tow it home. I already had a PMD extension harness since the one on the pickup was an all black wire item, making it suspect. I ordered a new PMD and put it and the ext harness on to get it running again. Later I got to looking closly at the old black wire harness and found a wire had come loose from a pin, cheap chinese junk. Now the new PMD is making me nervous and the multiple reports of new PMD failures doesn't help.
