Hi,

It sounds like you have nearly everything. What procedure was used to bleed the system? Also, do you have any assist at all? Did you use Mopar P/S fluid or equal? You can't use ATF.

If there are no leaks, the pump is turning, and you still have little or no power assist, read through the attachment below. Those are the bleed procedures from the manufacturer. Make sure you do it how it says.

Let me know if that helps.
