Ok i bought a h22 vx hatch everything is wired up already...
Problem is my injectors are not spraying... I have a resistor box wired up and it is wired up right.... I am getting 12+ at the positive side of the injector wire... So that leads me to believe it is the ecu not telling the injector to fire through the ground.. I thought it might have been the - wire from the injector so i wired the negative side on the #4 injector strait to the ecu pin that it goes to bypassing all of the wiring that has been changed and still nothing... the injectors are good the ecu is good i tried the ecu in my other car and the injectors by wiring positive and negative they work...
So i guess my ? is should i be getting 12+ at the positive on the injector should i not be getting less since it has resistor box? and if it is right what else could it be?

 

Ok i checked the pin from the ecu my battery is behind the back seat... anyway i checked the pins from the ecu with negative side of test light positive on battery and when i try and crank the car the light is flashing like it should be so now my ? is am i getting to much voltage at the injectors by the fact that i have a full 12 volts on positive side of injector harness? i have a resistor box so i would think i should be getting way less than 12 so maybe the injectors are not working because im getting a full 12 volts instead of less?
