I have just changed the clutch on my 2001 civic lx and the clutch pedal has no pressure i have already changed the master and slave cylinder and still no luck

sounds like air in the system try bleeding your clutch.

I have been bleeding it do you know how long I should take if you completely flushed the system

A pretty good amount of time heh. I'm not sure if they have the same set up but I know for my supra there is a small little bleeder valve (just like on the breaks) that you do a quarter turn on while having someone pump the clutch. Just like bleeding the brakes.

No you don't, you're just bleeding the system incorrectly. Here's how you do it.

Supplies needed:

2 brake fluid bottles, one empty, one full
length of washer fluid hose or similar, about 2.5 ft long
10mm wrench
an additional person (optional but helpful)

Put about 1/2-inch of fresh brake fluid in the bottom of the empty bottle. Slip the washer hose over the bleeder valve on the slave cylinder and put the other end into the near empty bottle of fluid so that the end is submerged. Open the bleeder valve and start pumping the clutch, adding brake fluid to the reservoir - you will have to pull the pedal back up, its easiest to just do this with your hand. Make sure that the rezzie does not ever empty. Once you start to feel resistance on the pedal, give it about 6-7 more pumps and then close the bleeder valve. Job done.

You won't feel full clutch resistance until the bleeder valve is closed. You will feel a noticeable increase from the resistance of the fluid moving through the system. By keeping that other end of the line submerged, you are making sure air can not get back in the system during the upstroke of the pedal. If you don't have a helper, limit yourself to 3-4 pumps, add fluid, 3-4 pumps, and so on until you feel resistance. If you let the rezzie go empty, start over and make sure you don't let it happen again.
