Looking for some quick advice. I have power steering “stock” for BPE and rack from FFR. I thought I bled the system well by filling pump and running engine while cycling left to right. I was getting ready to taking out for go karting and turned the wheel. It immediately went hard to left and vibrated back and forth (wheel stayed hard left). I turned car off and straightened wheel. Started and turn to right same thing. Went hard right and shook.

Pressure side of pump is connected to the upper port on rack and return is connected to lower.

What am I missing?

Thanks in advance
