Kirby G3 made loud noise when running. Sprayed silicon in fan thinking it might be a bearing. Found a coin and nail in fan and removed. Tha vacuum would not turn on. Replaced switch and brushes. Still nothing. Did the silicon spray do something?

No - the silicon is an insulating material and would have no effect on the electrics of the vacuum. Most likely you have a bad connection - dismantle the vacuum again and check the wiring and the motor with an ohmmeter. Be very attentive with the brushes, if they don't sit perfectly on the collector the motor will not run.
