So when i got the car the power steering seemed to work, but after high revs or burnouts the pump would struggle and whine. But reving up helped the pump.
Now i rebuilt my motor and did a cam and twin turbo, and changed the power steering rack because it was leaking but noticed the pump works when i start up from cold and at idol, but after doesnt work even if i rev up. No leaks or whines now, is my pump toast?
