Power steering not working pump is not pumping

first you need to remove power steering pump drive belt and fluid using a large syringe or siphon pump.then you need place drain pan under vechicle where power steering pump located,remove power steering return line and remove power steering pressure hose using a flare nut wrench,make sure drain pan catch power steering fluid. once you have the power steering pump return hose and pressure hose remove,then remove power steering pump mounting bolts then remove power steering pump.take old power steering pump and new power steering pump to machine shop or garage so they can transfer drive pulley from old power steering pump to the new pump,once you have new power steering pump ready to install be sure to buy new pressure hose o ring if equipped, you need to bleed power steering system once you have new pump in place with every thing back in place cant give you bleeding procedure you did not tell me vechicle type you working on.

POWER STEERING PUMP IS BELT DRIVEN PUMP LOCATED NEAR TOP ENGINE.LOOK FOR PUMP THAT HAS A RESERVOIR AND A CAP THAT READS POWER STEERING FLUID ONLY ALSO POWER STEERING PUMP HAS TWO POWER STEERING HOSE CONNECT TO RACK AND PINION.

You probably have hydroboost brakes and that system is powered by the power steering unit. If you have no steering and brakes, the first thing to check is the power steering pump. Check for low/no fluid. If the fluid is okay then the pump might not be pumping and you will need to replace it.
