I have a Mazda 626 v6 2.5L '98 120K. The power steering pump bearing failed and the pump eventually blew a seal and wasn't working. We put a new pump on but after about 15 minutes it would only work when the engine was revved. We thought that the pump was bad because it was a rebuild so we exchanged it for a new pump. Afer going down he highway about 150 miles with the new pump, then stopping for gas, the pump is not working again, or at least something is preventing the steering from getting power. When we put the pump on, we flushed and bled the system, put a new o-ring seal in and replaced the copper washers with the new ones that came with the new unit, and turned the steering wheel the 20x as recommended to get the air out. The system is not leaking and I have washed off all the oil that might have gotten on the belts during flushing. Do you have any idea what might be causing the power steering to not work? Thank you for your help.
