Rover 214 without current in the injectors

Hello friends of the forum.
I tell you, I have a rover 214 2 doors year 1997 and not part. The starting engine is starting. The ok benzine pump. Chispa also has the injection. Project the injectors outside 1 by 1 and they are ok. If Bencina made in the admission collector, it starts then until until the benzine that entered is over. There is no current or something happens that the injectors are not activated.
Any idea, steps to follow?
I would thank you for your help.
