Re: steering wheel hard to turn; power steering fluid is...
Intermittent hard power steering, at the begining of the turn of the steering wheel, once disturbed past the hard part, works normal.
Had fluid change, I notice a sensor, on the control block tower of the rack, is this at fault ? thanks buckleyeng.

Sounds like you are losing wheel speed signal when under hard turns. This is commonly caused by the harness at or near the wheel speed sensor has a bad connection of there may be a break in the wiring that intermittently loses signal to the ABS module and causes the anti-lock function to happen, (loss of wheel speed is like wheel skid as far as the ABS module is concerned) It is usually necessary to have a scan tool to monitor the data and read codes on the ABS system. You may have to take vehicle to shop that is capable of diagnosing the problem.
I do believe you must of turned the steering wheel too far to left or right, YES ? you need to turn the steering wheel as hard as you can toward the direction they are facing (your wheels) , at same time try to unlock your KEYS, you might have to put some effort into it, it will come !
would need to have a play but i would go for the idle control valve first ,then maybe the power steering where their is a sensor to increase idle when wheel is turned whilst stationary ,the sensor is on the rack housing where the steering wheel enters the rack
This probably isn't the solution, but are the wheels turned at an angle? Some times if the wheels are cut at an extreme angle when the key is turned off, their is rotational pressure on the stering wheel. That pressure may have the steering wheel lock in a bind. Try to turn the steering wheel to relieve this pressure as you are turning the key. Good luck.
usually if noise is made when turning right it would be the right wheel bearing easiest way to check would be to lift the car off the ground on that side until tire clears the ground and spin the wheel to see if it makes noise also try grabbing the wheel on the top and bottom at the same time and see if you can move the wheel back and forth checking for slack.
The steering lock consists of a hardened pin and it may not be releasing any more although it shouldn't interfere with the turning of your key, just your steering unless the Geo is done differently.
If it was mine, I would get a little rough with it and turn the steering wheel hard from left to right while trying to turn the ignition key.
Even disassembly is not easy since the lock area is supposed to be secure so it cannot be easily defeated.
