Check the red and white wire going to the injectosr for power if both have it, its either the injector, ground wire or the circuit ground driver for the injector not working

Check that injector solenoid resistances-Most likely its gonna be an injector problem-its not pulsing-meaning its not opening and closing to provide fuel to the cylinders

Well I switched the little cap things on the injectors to the side that wasn't working and it started shooting out gas so it can't be the injector so im starting to think its that cap thing I don't know whats its called.
