I have a 75' 260z,and the fuel pump will not power on,I have put direct power to the pump and it works,what can be the problem.Why aren't I getting power to the pump(all the fuses are good)is there something I am missing?Please help!

Pump only runs when the engine is running, a safety feature. On a 240 there are some relays mounted to the firewall next to the battery, one of them I believe runs the pump, I believe that the two that look alike can be switched for troubleshooting, don't remember what the other does at the moment. I don't know how different a 260 is from a 73 240, hope this helps.
