I kinda need help... fast

[ispoonwithmugen]

Well, as you may know, I was planning on working on the car this weekend, but I have a subaru tech at home who is free who will do it for free buttttt, there is a problem.. my car isn't starting now. I thought it was the starter a few days ago because I got it running twice with running starts and it started twice on it's own. I went to try a rolling start the other day and nothing happened. Today, I go out to change the starter and go to start it and again nothing. Try to jump it, again nothing. Any help would be really appreciated. It's sitting out in the baseball lot, and my dorm is right next to it so I can come outside. I need to be home either late Friday or early Saturday. So please if you can help me out
