Hi welcome to just answers my name is Ricardo pin 10 is a ground signal to the c/opn relay this ground energizes the relay field to connect power to the fuel pump did you repair the wire ?
the ignition module puts power on the field and the computer puts the ground to energize the field magnet on the relay and to bypass power provided by the EFI relay . this is a relay that connects another relay .
