Hiya, have a 2003 bravada(trailblazer/envoy etc) had a leaking power steeing line from a pinhole. Worked fine other than leak. I repaired the line and now no power steering? I have fluid pumping just not at pressure. What could I have done wrong? There are no kinks in the line or debris that I can tell. Could a pressure valve or similar in the pump be stuck or not working now? A little stumped here as all I did was repair the line and now no pressure. Thanks in advance!!

Did you replace a hose? If so did you use real power steering hose? If you just used fuel hose or something else the inside of hose could have swelled and is restricting the fluid?

You burned the pump up letting it leak and not fixing it sooner

put a vacuum pump on it

How did you bleed it, will it build pressure if you raise rpm?

You repaired a line? Not replaced it? How did you repair it?

I double flared and used a flare union. I found the issue, the pressure valve was stuck in the pump. Tapped on it and now I have pressure and steering lol.
