We parked the truck 3-4 days ago due to a loss of brake pressure. We'd dealt with that problem before, and know how to fix that issue, so that's not my problem. My problem is this: when we went for a test drive after fixing the brakes, we had no power steering! It worked fine before we parked it, and now it's gone. Some investigation revealed that the fluid was low. Filled it, and it still didn't work. More investigation showed no obvious leaks underneath, almost non-existent pressure in the power steering system, and a funny smell to the fluid. Not really a 'burnt' smell, but it doesn't smell right either. Is this likely to be a failed power steering pump, or something else? It seems a bit odd for the pump to fail while not being used. Any input would be great, thanks.

Try to pull the pulley away from the pump. If it moves, the shaft is broken. I've seen this twice, but I don't know what causes it.

If you moved the truck and turned the steering wheel without the engine running, the steering gear will push fluid out of the reservoir cap. That might explain the low fluid.

Can you hear any buzzing from the pump that would indicate it's pumping air? Do you have the diesel engine with hydro-boost brake system? If so, the power assist comes from pressurized power steering fluid. Have you run it long enough to bleed any air out?
