Power Steering Issues

The power steering pump is going out better of changing it than messing with it I'm sure it's a original pump

The steering problem is related to the power steering. Did you check the power steering fluid level? If level is ok, pump may be bad.

Hard starting is not related to steering issue. That needs to be diagnosed for fuel or spark issues. There many reasons for this.

Most likely is a weak power steering pump. This is actually pretty common and the pump is likely to last up to years before needing replaced. Make sure there are no leaks as this will reduce pressure through the system also causing this issue. If the oil in it looks dirty then it might require a flush.

Go check your power steering fluid level and watch belt turn at idle to see if it is tight and turning smoothly.Pulley could be giving resistance.mAYBE BAD POWER STEERING PUMP OR LEAK.

racket pion stiring is out replace it

power steering only works when motor is running. If car is running and you are having this problem it could be as simple as low power steering fluid...have it check...good luck and hope this helps some.

I'm getting the same issues except its only when my wheel is turned all the way to the right or left. I just replaced the power steering pump and tightened it, yet the screeching still continues.

Belt loose, tensioner bad, rack and pionion piston leaking internally, air in the system.

Sounds like your pressure needs to be checked for your power steering pump or maybe if that is ok the spool valve seals inside your rack are worn and letting fluid past under pressure.
