2006 g35 coupe 6mt won't start up
 

I was trying to adjust my clutch for my comfort, I took the clutch switch apart from the behind the peddle. It mad contact with another piece of metal and sparked, I gave it no interest so I carried on. After I was finished, i held the clutch down normally to start the engine and it didn't do anything. I've checked the starter and ignition relay as well as all the fuses. The car was working perfectly before I did this, what could it be? the key turns but it doesn't crank up.

I believe there is a sensor on the clutch pedal that tells the car if the clutch is depressed when it is started. Since you had a spark on the clutch switch (name ?) that is probably what happend--you messed up that safety feature and now its permanently on and won't allow your car to be started.

I would consult with a service manual if you have one, if not have the car towed to the dealer (if you can afford that route). Good luck.

Sounds to me like there's got to be a blown fuse in the box.
