Any clutch that is 'pushed in' is basically disengaged. When you push in the pedal, the two plates that compose the clutch assembly are separated from each other. If you have grinding when these parts are pressed together but hear nothing when they are apart, the problem should seem obvious. The plates are no longer working as they should and probably need replacement. One other possibility is that the clutch is operating normally and some other part of the drivetrain is damaged. The effect of this would be similar and would only be present when the clutch is engaged. In any case, an inspection is necessary to further diagnose the problem.
It may me that your brake is on.
Probably the Clutch Master Cylinder or the slave cylinder.
The clutch safety switch keeps the car from starting unless the clutch is pushed in. On the top of the clutch pedal there is a little black box with a plunger on it. When the clutch is pushed in the electrical connection to the starter solenoid is completed. The switch just unscrews from the bracket.
The pressure plate is not fully releasing (clutch pack is bad)
Many things, but a clutch bearing seems likely.
Your breaks are probably worn down or have sand or stones in them you might want to get it checked out at you car's dealership it could be serious.
because i pushed it there with my foot
If it doesn't move if in neutral, then it could mean the cable needs to be adjusted, or the clutch plate needs replacing.
The clutch arm is like a teeter-todder. The clutch arm sits on a pivot point in the transmission bell housing and disengages the clutch by pushing down on the pressure place through a "throw out" bearing when the clutch pedal is pushed down.
You may have a hydrolic clutch. One that takes fluid to make it work, check your clutch fluid.
put it in neutral then try to start it.
low fluid, internal bearing failure.
