First things first. Let's to a systematic troubleshoot... Have you checked for voltage on the large red wire at the ignition switch?? It's fed direct from the battery so it's "hot" all the time.. If it's ok, while you're under the dash, probe the purple wire with a test light.. Turn the key to start and check for voltage there... If no voltage, you have a bad ignition switch.. If there is voltage on the purple wire, move on to the neutral safety switch (NSS)... Should have voltage on both terminals with the key in the start position.. If no voltage on either, check the wire between the NSS and ignition switch.. Could be a broken wire, loose connection, etc.. If voltage on only one terminal, NSS is either bad or out of adjustment... If you have voltage on both terminals, move on to the bulkhead (firewall) terminal block.. Check for voltage on that purple wire.. There is a connector for that wire on both sides of the firewall.. If all is OK there, don't depend on hearing a "click" as the solennoid energizes.. Hire a lefthanded monkey to connect your test light to the small terminal nearest the engine on the starter solenoid.. Should be voltage there when the key is in the start position. If voltage is there, the solenoid is bad.. If the solenoid does indeed pull in, the starter motor is bad..

That's an explanation of how the starting circuit works.. You should be able to locate the problem with this information...
