Why would the first and third fuel injectors not be firing if the injectors themselves are working?

[Edit]

Answer

You might check the controller for the fuel injectors sometimes they can go hey wire you can use a multimeter and check it to see if it's firing in the correct order and if it's not you might need to replace it. Give that a try also check for shorts in the wires from the injector connector from the injector all the way back to the controller. Hope that helps. :)
