Car won't crank

Just fixed dead fuel pump. was working for a day and now car won’t start again. No cranking sound, No repeated clicks. One small click when key is turned but unable to locate. Battery at 12.6V, headlights don’t dim when key turned, current from solenoid small terminal to solenoid body and starter body. Yet to bench test starter. All fuses and relays have been checked. Any ideas? Do I need to bench test starter?
