Re: '91 Lumina Euro power steering failure

Spool valve in the rack might have frozen up, power valve in the pump may have failed....blockage in the lines...

Pump's not moaning or anything? When the engine's running is the fluid circulating in the reservoir, or just sitting there?

Also make sure the SHAFT of the pump is turning...seen a couple of GM pumps spin the pulley on the shaft (press fitted) but usually the pulley will fall off soon after...
