My 1969 Sport Fury convertible isn’t starting now

Alright so just recently bought a Sport Fury and ran great when it got up and running and one day when it was running it must of died and now nothing is working. When I turn ignition nothing happens no click nothing and I'm not getting any power from inside the car but was getting lights etc before it died that day I'm assuming a ground of some sort. So I then tried starting it by jumping the starter relay under the hood all it does is spark doesnt even get starter to turn over even when key is in turned to start position. So assuming somewhere inside something has went wrong cause I'm getting power up to the relay but doesnt even try to start itself up so looking for assistance on where to start looking for the problem. Thanks for any help someone can swing my way
