Assuming a chevy of some sort?

It sounds like it just needs to be bled. Jack up the front end so the tires are off the ground, engine running, turn the wheel back and forth lock to lock several times, making sure the reservoir stays full the whole time.

Are you sure there isn't a problem with the front diff? Something to cause it to bind up?

if i jack the front up or am driving it steers fine it's mainly at a stop or moving real slow

The one and only thing I can think off---some crap got into the pump and is floating in the relief valve--or the cavitation damaged the pump. You can pull the high pressure hose off the back of the pump--and remove the 1" fitting the hose screws into--thats the valve. Inspect it and clean it...
