Can anyone please tell me why after replacing the rack & pinion, power steering pump, IT STILL DOESNT WORK? Is there a reset button?
I would say you have a defective power steering pump since the rack is replaced. You did bleed the air out right? Raise the front wheels off the ground and slowly turn the wheels left to right and see if the air is bled out of the system. There is not "reset button"
Try adding a can of LUCAS brand power steering conditioner, it may cure the problem. Did you flush out all the contaminated old fluid each repair, if not change all the power steering fluid with fresh and then add the LUCAS product to top it off. That is all I can offer, next stop is the Lexus dealer service dept.

SOURCE: rack and pinion leak
It needs replaced a rebuilt unit cost $350.00 and you need the tools to remove the tie rod ends and you have to unhook the steering wheel, if you have a hoist it's not to bad but a do it yourselfer it's a pretty big job, the fluid is that color because it's sucking air into the fluid because of the leak and the shaking is caused by one side not holding hydrolic pressure because of the leak and wore out inner tierod ends. If you do do it you need a whole lot more information and much more instructions to do it, afterwords it will have to be alingned, having done it before and having the proper air tools I can do one in three hours. You might take a week but it would be a learning experince.

Try replacing a fresh power steering pump with yours. The used one may not suit your car. I came to know a site which has all car parts which includes power steering pump for your car make. Have a visit at this link.

I still need help !!! I have had my power steering pump aswell as the rack & pinion replaced for a second time to make sure the parts were not defective and I still have no power steering !!!!! The funny thing is that is sometimes just works then stops randomly....
Thank you so much Dennis, I will try this as a last resort, then off to the dealer if it doesnt do the trick.
