I've got a 4 cylinder, 3rzfe motor , 90 series and I diagnosed it as a fuel proplem cause it only starts with starting fluid then cuts off, there is good fuel pressure at the fuel rail. I used the test light on the injectors and both wire has power, while ignition is in the on position, ( I'm confused shoudnt one wire be the ground therefore no power should be there) im not sure which is ground, while touching one of the wire I can hear a relay clicking?
P.S; not really smart when it come to electrical faults
