Ok, I'm gonna start off by saying this. I am not, very mechanically savy. So with that on the table, I was replacing the Upper Control Arm on the passenger's side. I had trouble getting a bolt off because of wires and what I assume is fuel lines. So I disconnected a small black box nearby to open up some room, and after I finished, (and reconnected everything of course) the car refused to start. I had taken the car out before this so it did run normally. I do hear the fuel pump, and I'm inclined to believe that it could be a spark issue.
