Start at the Key, and trace it forward.

Is the relay on the fenderwell getting the keys signal to throw? Unplug one of the sm wires and see.

If not, and that relay is still sending Big Power to the Starter, THAT relay is Bad.

If so, the Ign Cly is Bad as it shouldn't be completing that circuit when Off.

If everything is OK with those two, then the problem must be with the starter, or the associated wiring connecting to just it.

my guess is the starter solenoid is shorted out internally..
