I don't know much about my car ( yet ).. But every now and then I go out to start my car to head out somewhere and I put the clutch down ALL the way, turn the key absolutely NOTHING happens. I let off clutch, push in again, turn key, and it works.. Sometimes i have to do it 2 or 3 times. While driving everytime I go into 3rd gear (no matter what) it grinds? What is up with that? IS there something wrong with my clutch?
