Well if it does not click there is a good chance it is just bad starter solenoid. The contact disc may be stuck open or perhaps the pull-winding in the solenoid is shorted or open. You can rebuild one, they are VERY easy to assemble or you can just buy a whole starter.
However, it sounds like your diagnostic skills are not the best (no offense) so maybe you should have it taken to a shop. If you think that you are proficient enough I can explain what to test to you. I have the OEM service manual as well as access to Alldata. Let me know and hope this helps!!
