i’m having trouble with my fuel system. car is a stock 08 si, i am not getting a ground to my fuel pump relay or my injectors. from what i have read (which is a **** load) the ecu controls the ground to both of these. the relay and injectors get a positive 12 volts while cranking. anything else you can think of besides a bad ecu would be greatly appreciated. the relay/fuses under the hood and under the dash are good. they receive the positive signal but no ground.
