Help me with my powersteering

I've got a 97 Tacoma 4x4 5speed 2.7l that has no powersteering. I've put 2 new pumps on a new rack and nothing. It has power steering when the wheels are off the ground but as soon as it hits the ground its gone. Idk what's wrong. I'm guessing the high pressure hose is messed up. I did clean the resvoir already twist and found black in it. So idk someone help me plz

 

I have 99 tacoma and dealing with power steering issues. There are some videos on bleeding the system and a post about taking apart the reservoir to thoroughly clean the internal screen. Definitely clean the hoses,check them and make sure the pump does not run dry at all when you start it up.

 

I all ready took the reservoir apart and cleaned it 2 times and bleed the system 3 times and it works with no pressure off of it but when I put wheels on ground and it stops working

 

We'll most everyone was right. I took the screen out of the reservoir and now its fixxed. The screen looked perfectly clean but I guess it wasn't. Glad to get it fixxed

 

does anyone have pictures of taking about the factory reservoir? i'm dealing with the same issues and can't find an aftermarket reservoir. any and all help would be appreciated. thanks in advance. josh

 

All I did was take a flat head down in the hole u pour fluid into and busted a hole into the screen and it fixxed it

 

thanks for the update. i actually took the oem reservoir apart and used a pic to remove all the filter screen material in the bottom of the reservoir. the inside of the reservoir was caked with black "scum" which i managed to clean out with two cans of brake cleaner. i took before/after pictures that i will upload in a couple of days. i will try to write up a description of how i did everything once i post pictures.
