Have you been doing maintenence? Possibly if the cylinder loses spark it will keep the injector from opening. You said it doesnt do it all the time, so it could be spark related. But if you really want to rule it out, you can swap injectors from a different cylinder if you can do that yourself. Make sure to bleed out the pressure or it will spray. If you still have a problem on the same cylinder it points to controller.
Please consider a to help us answer more questions.
