Diagnosis is the major element in the process.
1} When "nothing" happens is there lots of current flowing? (use a starter current meter ~12-18$ at the auto/tool store, pushes against the battery cable and reads in hundreds of amps.) If the current there is in the several hundreds 400-600, there is a direct short to ground, either in the starter, or the heavy wiring to the starter.
Have starter checked.
2} If no serious current, then the starter may be open (no conductivity inside, ergo bad brushes or similar open circuit). Or the solenoid is open (bad) To check this (again if no serious current) check to see if full voltage is on the starter side of the solenoid when the key is turned to start (momentarily)
3} Also if no serious current the start terminal (small with S usually) fron the ignition switch may be tested for voltage withe the key to start (momentarily). If none then the circuit to the key from the starter (usually a smaller #10 wire leading from the battery side of the solenoid to the dash area) through the amp gauge, if it has one, to the key and back to starter may be open.
Good luck, JimN
