If they had (it is called an inertial sensor, the impact is for the airbag) behind the left fender structure, inside the engine bay, where the shock absorber is mounted, but this sensor only canceled the positive of the relay in case of shock to cut the bomb, If there is no injector or coil pulse check the rpm sensor that is mounted on the top of the gearbox on the flywheel. I wanted to upload a photo of the location but I can not, they have changed the procedure and I do not know how.
