On my 2001 +8 there is only one relay under the bonnet which is for the radiator fan. I was said that the electric fuel pump is directly driven by the GEMS ECU.
The only failure I ever had was a bad contact at the fuel pump lugs. They were completely charred, blackened by the arcing that occurs at that point due to the high amperage.
A simple energetic cleaning with sandpaper solved the problem by restoring a good contact. Better to have a look a these tiny lugs.
