No Fuel to my 20

I'm not getting fuel to rb20. someone gave me a 300zx fuel pump but that will not work. So i orderd a walbro 255. I also ran the wire from the fuse box to the ecu (pink black wire??) Anyone got a solution

the wire does not go to the fuse box from the ecu it goes to the (assuming it's an s13) to the same color wire at one of the 2 connectors beside the battery tray , the ones by the blue relay in the corner.
