Default Power Steering unrepsonsive !!

2004 STI, new pump at 80,000. Car currently at 112,000. I just finished replacing the hardline banjo bolt crushwasher, o-ring, and reservoir lines. I manually bled the system by turning the wheels side to side until there was no bubbles left. Adjusted the belt to spec and topped off with ATF fluid.

BUT now when I start my car the power steering is stiff and won't even kick in? Could there be more air trapped in the pump? Would over tightening the crush washer be a cause to this? Is my pump screwed?

I have attempted to bleed the system multiple times with no luck. When I turn the car on the pump is completely silent and I have no assist at all. The pump was working fine (other than a small air leak) prior to all the replacement parts I installed* Also the rack and pinon has about 30k on it.

*Other parts I installed at the same time, but not directly relating to the pump: mishimoto ancillary hose kit, mishimoto turbo inlet hose, mishimoto intercooler hoses, new oem turbo, and new evap hoses.

All hoses are in the correct place. The reservoir has maybe one or two tiny bubbles, but nothing like a foam.

Could it be possible that there is some stubborn air stuck in the pump? How many times should I manually go lock to lock?

if you held the steering at full lock for any period of time you may have killed the pump doing that

Sh**, I don't know what happened. I'm going to remove the reservoir and look for any potential blockage and completely flush the system. If that doesn't help anything I'll have to buy a new pump.

One noticeable difference is that I replaced one of the reservoir lines with silicone line from mishimoto. Not sure if that would screw with anything.

Definitely what I was pondering. I've went ahead and ordered the oem part. Here's hoping it's part of the solution.

Well, after removing the suction hose between the pump and reservoir, I realized I had made a (potentially dire) sloppy mistake. I had been using a vacuum plugs to keep fluid in and crud out while I worked on my vehicle. Seems that I had missed one. I am totally kicking my ass for this, as I am usually insanely meticulous.

I removed the plug, put the hose back on, manually bled the system, and started the car (with the wheels up). Pump doesn't seem to be making any weird noises or leaking, but it is being a pain to get all the air fully out. I have yet to know if I've bitten the bullet, but everything seems okay for now.

Thank you for all your help and troubleshooting. I really appreciate it.
