Clutch pushed in but car wont crank
 

So I got my master clutch cylinder replaced a couple days ago and now sometimes I will pish in the clutvh but thr car will not crank at all can someone tell me what the problem os

I'd start with testing the clutch start switch. It's the push button switch which mounts to the fire wall and SHOULD be pressed when the clutch pedal is pressed all the way down.
