Check the fuel pump connector even gets a 12v signal, just the fuel pump harness ?
If the pig-tail is dead, remove it, then measure the “main bike harness” itself before it connects to the “sub harness” of the fuel pump. Want to make sure all the wires from the pump down to the ECU is not broken ?
If the pump had a pink wire , i would trace it all the back to the ECU which i assume it should still be the same colour (Hyosung does change wire colors halfway down the harness! so verify with service manual book that has a wiring diagram at the last pages)
