Sounds like wiring or signal not being either sent to the starter or ecu, assuming Speedo lights up with ignition turn.

Sounds like a battery that for whatever reason was discharged during the work that you done. Recharge the battery and check again. Because of the case, (low volteg) you may find some error codes, delete them

Messed up wiring is guess. It's probably seeing a nss (neutral safety switch) from the old auto tranny wiring indicating the car is in gear(not neutral or park) so it wont even turn over
