to whom it may concern

I have a 2004 impreza wrx. 82k mint condition
I recently noticed at start it was sluggish turning over. It did start 1st crank, but sluggish. Thought it was a battery issue.
Now it wont turn over at all . Clicks a lot but nothing, assuming solenoid clicking.
I have 12.39 volts at battery so I'm pretty sure its not a power issue.
not sure if its the starter or not. fuses seem to be good. relays i have no clue.
Please help
