| do an on car test of starter to duplicate the load of the engine. Down by the starterr unplug the starter lead to the solenoid and clip and tape to insulate on several feet of 12 ga wire. Then turn key to the start position and in neutral touch the wire lead end to the + batt terminal for a second or two. That should start the engine: (1) If no start the starter is bad under load or a bind in the rotation; (2) If + test there is a wiring issue between the starter solenoid connector and the ignition key. If (1) have starter checked at a starter rebuild shop not a auto parts supplier like Pep Boys, Auto Zone etc. If (2) then start from the starter connector and check the circuit for continuity. Note that even if continuity checks OK the wire or connectors may not be able to carry the current to excite the starter. Did you use OEM for the relay replacements?
Note relays can check OK with continuity and 12v excite but they fail under current draw, happened to me. Report back results
