Emergency! troubleshooting '01 PSD power steering / breaks out
I have a 01 PSD extra cab 4x4. I had a whining power steering pump so I printed the guide to flush the system. I had the hose off at the hydropump nipple and began the flush. The reservoir never emptied and only about 6-12 Oz of fluid came out. Fluid was gross and a bad color. Anyway, the reservour never drained and eventually even pumping the brakes or turning the wheel wouldn't cause it to drain. I let it back down off the jack and as expected the power steering is out and so are the breaks. Where can I begin to troubleshoot, or is definately time to replace the pump? Please help! Thanks.

What noise is the pump making? If you can get a mechanic's stethoscope or improvise with a long screwdriver, listen to the pump through contact. Additionally, (not to offend), have you added more fluid into the PS res? Are there any visible foaming in the PS res. Take pictures if you can. We'll get you there. Hopefully they heavy hitters will be here soon.

Sounds like your pump just went, strange it would do so when you add in new atf.
Well...
maybe try siphoning off the new fluid and look down in the res. If I remember right, there is a screen of some sorts, it may be clogged (if it exists). If not you can start to see the intake to the pump. It's worth a shot.Just a check here, no fluid leaks anywhere? Also, are you on jackstands? I will assume you are, if so, does steering move at all without the pump.

Try the siphoning thing and look for the issue. Again, would like to see a pic or two if possible of the pump res with the cap off and the ATF that pumped out. Did if ever start to change color when it was coming out? What was the color of the fluid in the res when you pulled off the cap?

Ugghh... I just thought about this, it is possible your pressure control valve crapped out causing bypass. It's on the outlet of high pressure side of the pump. Another possibility is the veins on the pump encountered something that broke them off, but I would think you would hear some rattling as the pump spins. I will look for a video or diagram that shows the internals.

Google-Fu is strong tonight.....
Show an cross-section of a pump. They all work pretty much the same.

Could have been the original. Truck has 338k on it. I bought it with 332k. I was about to buy a pump that says without reservoir. My truck already has a reservoir on it (so I assumed), but the ones with reservoir for sell looks like the reservoir is actually on the pump itself, and and not like mine (so I assumed). Now I am thinking I added ATF to the wrong reservoir and may have ran mine dry. I FEEL DUMB. Is this picture I attached the wrong reservoir for the adding the fluid? (note that the picture is not mine, and that beautiful red fluid is what Im trying to achieve)

I don't see a picture, but if it's on top of the master cylinder then you did. This red is for brake fluid. The ps red is down by the pump and sticks out toward the driver side. The brake fluid res is high and in the back driver side of the compartment. If you did this, please let me know so I can give you a solution.

Watch Trey's video. Is this the procedure you followed. Did you add where he puts the funnel? If not. it's worth checking level there, and trying again. Then you may need to address the brake fluid.
