S300 pump wiring with no main relay
Posted: Thu Jun 25, 2015 12:12 pm
So as far as i can tell right now, my fuel pump isn't priming or running. the car is not wired with a main relay but like the attached. I don't hear it prime or run when i flip on the accessory and main switch. Does it need a sensor power input to keep it running once the engine starts along with the A7 pin from the ECU? Or does and will the A7 pin prime and keep running?
