77 280z fuel pump not getting power
 

Hello I have been trying to work on my 280z lately. It ran during the winter perfectly fine but a month or 2 ago it stopped working. I have tested the fuel pump and it runs fine but won't run when I'm trying to start the car. I checked the fuel pump relay and internally it all looked intact. My father and I are lost now and don't know where to look. We have a couple old manuals and have tried getting schimatics off the Internet but still not sure if what we are doing is correct. Just to clarify the fuel pump relay is 2 relays in 1 that is right above the hood release latch on the 77 models? Thanks to anyone that is willing to offer help it is very much appreciated!
