The 1.4 MPI what usually fails is very much is the ignition module-bobbin, but not also forget that so that it works and throws "spark" also carries a "hall" in the one of theco and it is also damaged, (this is when the engine turns and does not start ...) I do not know if I understood well if the starter turns to turn when turning the key, if not, try to give the engine to start a hip. If it was bad "brushes" and that is why it does not turn, it rules out that it is the key encoded. Another possibility would be to look that it is not a problem of the key of the key itself (spent contacts), greetings !!
