So this happened out of the blue, I drove home for lunch from work and everything was fine. I parked my car at home. Then when I was trying to leave to go back to work, my car wouldn't start. I have no background about cars whatsoever. The radio turns on but it makes this noise when I crank it. I don't really know what to do. Thankfully, we have an old spare car that I took back to work, but I don't what's wrong with my car. We're gonna try and jump it later with my coworker but I'm trying not to get it towed and spend a lot to get it fix. Please help me. I asked around and they said it might be the battery, or starter or alternator or the feul pressure regulator but im just lost. I took a video of it. Please help me out
