SR fuel pump help ( not working )

ok

no oil to the top of engine = fixed
no spark= fixed

no fuel = pump not turning on but when i hot wire it starts.

4 wires going to the fuel pump relay 3 are positive but the one that is suppose to come out positive is comming out neg i heard something about wrong ecu wiring ?

i have read on the internet that my fuel pump needs to get rewired i had my sr harness made to fit my s14 by auto dream but im getting a neg signal on the wire that is suppose to be positive i need to know how i should rewire this so it will prime on its own and turn on when the car is running and off when i stop it . dont tell me just to wire it to an ign wire cause it will run all the time when im just listen to music so thats no good.

i have heard this is a problem most sr swaps come into but i cant find a good source of info to help me
