Not sure on the Vibes, but I know on Mustangs they have a clutch
starter interlock switch attached to the clutch pedal. It has an adjuster on it so you can move when it will engage the
starter. If that is the case, it has just moved to the limit of it's adjustment and you should be able to adjust it back some so you can start it with less travel. I'm sure someone with a manual Vibe or wiring
diagram can confirm.
If your clutch is going out, it will most likely be slipping. Try stopping the car in 1st gear without disengaging the clutch. If the motor dies pretty quickly, then your clutch should be ok. But if it chugs along and keeps trying to run for a few seconds, then likely the clutch is slipping. My Mustang does that, and one time it was so bad, I could not drive up a driveway incline without a running start!
