Fuel Pump Relay Location on 500SEC Euro?

Hello everyone,

I left my 500SEC in the garage for a couple days this winter when it was very cold (below 0) here in Wisconsin, as I usually do in winter, but this winter we didn't get much snow early on so I was driving it for a little bit while my van was in the shop. When I went out to start it after the weekend, it wouldn't go. So I figured gas line freeze, which is common out here, and forgot about it for the winter, seeing my van was fixed later that day.

Now that spring has rolled around I wanted to take the car for a spin and found that it still won't start. After some checking I realized it's not getting fuel, and it doesn't sound like the fuel pumps are kicking in. I had this problem with my old '86 560SEL and found a bad solder in the fuel pump relay to be one of the issues. So I thought this would be a good place to start looking, BUT I CAN'T FIND the fuel pump relay. In the 560SEL it was pretty much right next to the fuse box, but not in this SEC. I checked the Chilton manual and it doesn't show the location of the relay. Does anyone know where to find the fuel pump relay? Please note the car is a 1982 500SEC AMG European model, which seems to make good service information (or any information) hard to come by. Or does anyone have any advice on what else to check for to diagnose the problem, assuming both fuel pumps are good?

Any help would be greatly appreciated, as I'm just itchin' to get out of the minivan and into the AMG.

Thanks,
Dylan
