I’m getting a engine code 43 (fuel monitoring system) I believe I not getting a ground to my fuel pump relay from the ECU

this started out as a dead battery I put a new one in and then it would not start I wasn’t hearing the fuel pump come on so I pulled the pump and hard wired it and it was shot so I put in a new one and I didn’t hear that one come on and prime either so I pulled the relay and tested it it was good so after scratching my head and fed up volt testing I found I was not getting a ground to my fuel relay so I sent a ground from the battery to the relay and it fired right up rode around a field for about 15 minutes or so with zero signs of any issues turned it off cranked it up later and the check engine was on and shows code 43

am I missing something or is my ECU shot??? I’m About ready to put it out on the curb lol
