Well it immediately started this morning no problem, so didn't need to use my backpacked toolkit.

I removed the OVP. The socket and pins are clean and dry and free of corrosion. No rattling of anything inside. Both of the 10amp fuses look good and ohmmeter test good.

Removed the fuel pump relay. The relay pins are clean and dry and free of corrosion. No rattling of anything inside. But the socket looks like maybe trouble. A couple of the sockets are kinda loose in the plastic block, as if the surrounding plastic has melted away or disintegrated away or something. Specifically, the socket positions which mate to relay pins #30 and #87k are a little loose in the plastic block, instead of being solidly held like the rest of the positions are. But on the other hand, once the relay is plugged in tightly, those big sturdy pins should hold everything in place, loose sockets or not.

I've seen threads about people repairing fuel pump relays by resoldering bad solder joints. I don't see any solder joints. Do you have to disassemble the relay to discover that? Mine doesn't look like it snaps apart.

Any further advice and recommendations will be appreciated.
