'91 Subaru Justy won't crank

[Eylan]

I have a '91 Justy that won't crank but all other electronic components work. My original thought was it was the battery, and it was not, I tested it and tried jumping it aswell. Next thought was it was the starter, after replacing it I found that the starter was not the solution. After hours of google search and reading the Subaru Chilton I thought it was the ignition switch... sadly still a no go. I'm sitting here thinking it could be the starter relay but I can't seem to find any information on the topic. Does anyone have any ideas on what it could be?
