Did you remove the flywheel? If so, it's possible that the flywheel isn't seated fully against the crank and the ring gear is out of range of the starter throw.
To check this you could measure from the starter block mount face to ring gear distance and compare that with the starter mount face on the starter unit to where the gear is located with the solenoid actuated.
This could also happen if you changed the rear main seal and it didn't get seated fully and subsequently the flywheel didn't tuck in completely to the crank face. Alternatively if you heated on a new ring gear depending on the design sometimes they can be installed backwards which would also put them out of reach of the starter gear solenoid throw
