I have a 2000 Celica GTs, 2zzge engine, There is a wire on the neg side of the battery that goes down to the chassis. It then splits into two, one goes to a grounding point on the tranny and the other one goes to what?! Can wont start due to the fuel pump not turning on. I’m thinking this wire ground some ECU circuit or something. HELP!!
UPDATE: Fuel Pump wiring from relay to pump turns pump on as it should,“ground wire” is grounded to chassis. But the pump still doesn’t turn on, any wires I could has easily missed?
