Strange fuel pump relay issue

[pepe123]

Ok let me start off with it's a 89 240sx hb, with a dohc swap.

Ok what's happening is my fuel pump isn't turning on, I'm guessing because the ecu isnt sending out the ground signal to the egi relay, I had this issue before but then I moved around some wires, fuses and tightes the ecu plug and the pump kicked on, but the other day my battery died and i charged it and now my pump won't prime or go on UNless I bypass the Egi relay but putting wires where the relay connects. I think that's strange. Could it be a break in the black/ pink wire in between the ecu and relay? Also the pump fuse gets power like normal.
