Fuel pumps relay

[Buciraco]

I am hAaving a problem with my 560Sl 89 model, I start the car after 4 minutes it dies, I donīt hear the pumps runing any more, after some reseach at the old post I diceded it was the relay, whent ahead took the glove box out, now the question, what are those two silver relays for?, one of the big ones syas clima on it, most likely air conditioner, the other one says 8 zyl, 6000rpm, most likely the fuel pumps one, what is the other big one for. it says idler speed control 8zyl. Is there any way to jump some wires here to test my theory? is the 002 545 16 05 number on the relay the rigth one? date on it is 20 jan 89 so is the original one.

Thanks in advance
