When you turn the key to on do you have dash lights and gauges? May need to check that battery connections are clean and tight.
Also if you look on the pass side inner fender you should see the starter relay. You could jump the two big terminals on it with a wrench or similar and see if the starter then runs.
If it does then you may have a bad neutral safety switch (if auto) or bad clutch interlock switch (if manual). If auto try moving the shifter to Neutral and trying it.

Not good on electrics but maybe take the lower steering column shroud off and check that the rod that connects the key switch to the ignition switch is moving properly when you turn the key.
Also there is a big bunch of wires all connected to one big terminal on the fender mounted starter relay, some are fusible links, check that they are good.
