Guess some just like to start looking at the wrong end.

If the fuel pump relay isn't working it is either not getting power (could be a crank sensor problem) or maybe the relay is bad.
I haven't seen that you have checked the fuses (Fuse Panel 3) in the back of the DME box yet, there are 5 fuses there, F2 is for the fuel injectors.

Testing a relay is easy, apply 12 volts to the coil pins. Put one meter lead on the common pin. The other lead goes on the NC and then the NO pin. You are looking for the contacts to make and break when the relay switches. The ohms scale is used.
