I installed a new faucet in my kitchen and I'm getting very little water with no pressure.

What's the brand and model? Is this one of those water saver type faucets?

Remove the faucet aerator at the end of the spout first... clear it, run water without it in place and see how water flows. If water flows properly without the aerator in place, clean the aerator and replace it.

Otherwise, if that doesn't help resolve the issue give the information as requested by Hkstroud.
