there is a wire you can splice a resistor into that will make it so you can start the engine without the clutch completely depressed, but that makes it easier to start the car when it's in gear, which can be very harmful and even cause a wreck.

gauging from how you're already having trouble with the clutch, i'd suggest you don't do that and just grease up the pedal to get the squeaking to go away.

always press the clutch all the way in. you're not in a drag racing funny car, be nice and easy with it and sooner or later you'll be caressing it like it was your sunday office sex buddy.
