Checking the clutch

You can check the clutch switch with a multimeter when it wont turn over make sure the car is in neutral ebrake on clutch pedal to the floor make sure the pedal is depressing the clutch switch there should be battery voltage to both the wires to the switch with the key in the start position. If there is only power to one wire bad switch. If there is power to both wires I would check and see if you have power to the little wire to the starter with the key in the start position.
