Do you mean that the car will not shift into first? The clutch is the left pedal on the floor and should work independently of which gear is selected. If the car will not shift into first the clutch may need to be replaced, transmission synchros or gear teeth for first gear could be damaged(chipped,missing or broken) or the shift selector shaft might need to be realigned and/or have it's bushings replaced.
Your clutch is slipping.
if there is a clutch adjustment on car, adjust the clutch if no adjustment, you will shortly need to replace the clutch
The clutch is bad or out of adjustment.
my clutch went to the floor what happened?
My first suspect would be the clutch. Have a competent mechanic take a look at it.
The manual transmission has a starter interlock which prevents the engine from cranking unless the clutch pedal is depressed
The clutch is shot or in need of an adjustment.
Sounds like you have clutch issues, check the hydraulic clutch fluid level, if it is low you have a leak.
Your clutch isn't releasing entirely.
clutch wont work will also leak fluid
It is either worn out , glazed, or there is a fluid leak in the bell-housing , or clutch enclosure.
Assuming you mean the clutch won't disengage and the system has been bled properly, the pressure plate may be damaged or the clutch disc is installed backwards (if the clutch was just replaced). Also, with some vehicles the clutch master cylinder has to be bench bled before installation.
