Alright sc friends and brethren I searched for days trying to find info on a case similar but still havent really found my answer. But I really needs some help. Ok so I have a 92 sc400 1uz of course. Mind this is a drift car so its not driven daily. But when I first got the car I initially had trouble with my fuel pump not priming finding the cause was my fuel pump ecu. Did the 12 volt mod to bypass it and had no issues. So Pump runs as soon as the ignition is on. Then a week later went out to start the car and nothing. Checked the wires for the bypass and they're fine. Checked the efi relay and fuse, and injection fuse fine as well but no dice. I currently am getting no power to the pump or fuel pump ecu. Thought it was my main ecu being that it had capacitors leaking but i got a rebuilt one from a guy on here and still nothing. So we decided to jump 12 volts directly from the battery to the fuel pump ecu wiring doin so made the pump run. So we tried to start the car but the car only wants to try to run if the ignition is held over even then it misfires like its not getting enough fuel. so now I have this issue and no power to the pump. Does anyone know what this could be? I don't understand it car drove fine one day parked it and came back a few days later to all of this. Can you guys help on in desperate need to get this car back up
