"76 fuel pump ballast bypass relay, open or short detected" but I didn't think a 91 had one. THe other codes are all relay related as well. I would start looking at ground connections and the PDC where ther relays are located for a common problem.
Not to worry folks. Those are the codes you get when the timing is out 180degrees. Now I know this. Cranks, runs well, resonator sounds great. Sorry to bother all of y’all.
