At first it was making noise and it was hard to turn the wheels at idle, but then it completely lost power steering and noise. I replaced the pump but still not pumping. I have the return hose disconnected to flush or clean the old fluid but only a little bit of fluid came out,Like three table spoons.The pump has an electrical connection on the bottom on the pressure side hose that looks like a coil. Could that be bad not letting the valve to open to circulate the fluid? Or am I wrong and that's not a valve.If I connected the hoses backwards on the gearbox, will that cause the pump not to have pressure? I'm not sure what's wrong, the engine is running but I have no power steering at all and no noise either.Help please.
