I’ve had wiring problems before and I fixed them, now my starter won’t engage after 4 months in my 91 ls400 it feels like there’s a bad ground somewhere. I’ve checked the harness in the passenger side fender well plus changed the battery, terminals, tested the starter relay. I feel like it’s so simple but I’m at a loss. If anyone’s had this problem and they’ve fixed it plz lmk
