89 Not starting electrical? Main Relay?

[pearlwhiteS14]

I have a problem with my car not starting. THere is power but when the key is turned the engine just give one click? After a few times of trying it the engine then turns overand starts with no problem. Must be a connection or main relay is not working right? What other ideas does anyone have? 89 ka24e stock coupe.
thanks

could also be the starter take it out and have it tested at autozone if that is ok then check the relay but i would guess it is the starter itself
