CLK 430 fuel relay

My 2000 CLK 430 cabriolet shuts down and won't restart for 30-45 minutes. When it does this the fuel pump doesn't turn on. I believe this to be a fuel relay. However, I'm not sure which one it is. Help please

Most likely a crank sensor issue, no crank sensor no fuel pump.

The fuel pump relay is in the trunk.

On drivers side, top of the trans bell housing; usually able to be seen from above. Reaching it is another matter.
