09 flex sel. Lost power steering. I installed a new rack and pinion, new power, steering pump, lower control arm, front struts, and I still have no power steering. Any help or advice is great. Im Lost at this point. Thank you.

 

When you purchased the replacement power steering pump , it should have come with directions how to get all the air out of the system.

Did you perform those measures to get the air out?

Usually, you with the front wheels off the ground , engine running, turn the steering wheel to both extremes several times ,slowly, to purge the air from the system.
Also, make sure you use "Power steering fluid". It can handle the higher temps the system creates.
