F4i Relay Issues NEED HELP!

I really need some help on this one. So my fuel pump won't prime due to the unknow. The bike ran fine no issues except code 7, which is coolant temperature sensor. And also I got code 23, which is o2 due to me having aftermarket exhaust. Now with that said my brothers f4i fuel pump relay went out and I gave mine to test it if it'll fix the problem. It fixed his problem but when i put it in my bike the fuel pump won't prime. So we put it back on his bike and it worked! I bypassed the relay by jumping a brown and black/white wires. Fuel pump starts priming nonstop and I can start the bike just fine. So far I have checked all of fuses they are all fine, checked ignition, kickstand, tip over sensor, and its all good THE RELAY JUST WONT CLICK, my engine stop relay clicks but not my fuel relay, so i checked voltage and i get 12v to the relay from brown and black/white wires i also get 12v from white/back brown/black, but when i connect the relay i get 12 v from brown and black/white, but i only get 1.08 volts from white/back brown/black This is pissing me off! Can someone help me where can I look into. Im Going to a shop right now to buy a new relay may it's my relay tripping but it doesnt explains why it works on my brothers bike but not mine.
