Now after coffee! So, we can come down to the well known equation; P (watt) = I (current) squared x R resistance. With ageing of the relay contacts every time we cut off the engine we get more and more pitting and soot there. Resistance will increase becase of these issues and
as petrol pump still needs its precise current to operate well, we will have lots of watt here. With time it makes energy which will be transformed into HEATH....glowing heath. Thatīs not good for the contacts as we can see from your first picture... the purple wire. I would guess there must have been many hundred degrees C to create that color. Strange that the silvery part of the contact isnīt blueish...they usually become that when heated.
I belive we have hit the nail when coming down to the DME-relay issues. It would be a good thing if we could solve this by simply connect a capacitor between ground and pin 87b and pin 87 as well (moving part of contacts). I will go an buy a couple for use in old time distribu-tors if it still possible to get them. Its onother story where to hide them.
Best regards.
