My husband drives a 92 chevy cheyenne standard and it needs a clutch what to do?

He has already changed the clutch but we have no pressure to the slave cylinder why is that any ideas???

If you have no pressure to the slave cylinder, you most likely need to make sure there's enough fluid and there's no air in the line (do this by bleeding the clutch master cylinder. If that still doesn't work, then something's wrong with your clutch master cylinder. It'd be unlikely, but make sure the lines have no holes. If that still doesn't fix it, then pressure to your slave cylinder isn't the problem.
