So today, i tried to start up my car to go to the gym. low and behold it didn't start. The battery works fine, lights work fine, battery even makes that start up noise like its trying to start up. I had a friend look at it and he said it could be either the fuel filter (Few days ago my friend was revving the engine pretty hard, thinking that could possibly be it) or a simple part thats broken/malfunctioning. Was wondering if anyone had some insight into this or if it happened to you what you did to fix it. Car is a Toyota tC Scion 2008. Any help would be appreciated!!!!
