Problèmes avec un Xantia

It results, I have an automatic bencineer Xantia 2.0 year 94, and it only generates a spark in 2 cylinders, the medium with a oscilloscope and one of the transistors (because it is Dis) that go in the ECU does not send the signal to the coil, try to get it and I could not, they offered me a used CODE OF THAT ECU, (the car is with a number keyboard), or how to deactivate the immobilisateur. Si quelqu'un peut m'aider, je l'apprécierais
