fuel pump relay circuit problem 200 1983

"Does this mean that I've traced it to the circuit to the ignition switch or the switch itself? And, if so, what next? From the wiring diagram it looks like 15 on the FPR connects to fuse 13 and goes to the ignition switch if I am reading it correctly."

I find it easier to think of the voltage as going in search of a ground. So it goes from the battery to the ignition switch to fuse 13 to relay 15 to the relay coil to ground at relay 31.

If you don't have it at relay 15, my money is on fuse 13 -- or possibly weak, corroded fuse 13 contacts. It wouldn't be the first time that fuse has caused a no start. It's not common by any means, but it does happen.
I'd say you have it just about nailed.
