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.

It's possible. You should get a multimeter with continuity sound and check to see if the wires have continuity. It's possible the relay is toast, you can possibly try another relay.
