It sounds like it might be two problems to me. I assume when you turn the switch longer you might be turning harder also. Strange electrical symptoms when turning the swith almost always mean an ignition switch (electrical part) problem. I'd look at this first as it may cure the other problem (no cranking). Secondly, if you hear the starter solenoid click, but no cranking, it's probably a bad starter. Another common problem - especially on automatics.
