Which wires? What color? What pins? Relay coil or relay contact power? If you want good help, you have to supply good information.
The fuel pump relay is powered by two places, one from the ECM (grn/wh), supplies +12v to the relay coil for 2 seconds when you turn on the ignition. The second supplies +12v to the relay contacts (orange).
