Clio 1.2 No Pulse of Iny

Good afternoon friends, I have a CLIO 1.2 16V that has no pulse in the injectors, if you have ignition spark. Control the lines of + and mass of the ECU and the wiring of the injectors and it gives me everything well. The question is: the rotation sensor works because otherwise I would not have a spark, something similar happened to someone? What are I escaping?
Of course, to the discomfort of reading my post and welcome all suggestions.
