My 206 does not start

Good night
I have a Peugeot 206 2.0 GTI 16V. That does not start. I have proven the fuel pump and the fuses and everything is fine, although I notice that when I give the contact the pump does not act. They told me to change the impulse sensor or position sensor of the crankshaft, but nothing. The engine moves but does not start. I walk a little lost, if someone could orient me what it can be or that I have to check. Thanks beforehand.

The pump should act when giving contact, and you say that it does not go (this is independent of the crankshaft collector), I would look at injection relief (it is responsible for activating the pump and ignition) that comes power current, of being that no, it will be necessary to think if you do not have any problem with the immobilizer (transfers in key, anti -barn module, collar wiring that goes in this module to the start of the start. Anyway you can try feeding the pump with two direct cables and start ... if you have not already done it. Greetings!!
