Ok this is my 3rd power steering pump on the car. I have bled it and fluid is fine....but problem is car still is VERY tough to turn when sitting still and at very low speeds and feels as though i have no power steering. Even going around turns and what not you can fell the stiffness and it wants to pull . I am at a loss here and not sure what else it could be?? or what can i do to fix this problem. I assumed it was the pump but its still not right at all. So hopefully someone will chime in here and maybe list other things i can buy to replace to fix this problem.

TIA

Mine too...

There's a few things that this could be. I have some information that I need to dig up because my car is doing the same thing. When mine becomes hard to steer one of my warning lights come on. I have not driven my car so long (since November of last year or there about) and I can't remember which one it is. From my recolection there's some solder traces that actually behind the dash cluster and connected to a certain circuit.

Man I'm sorry I can't remember what they are but I will definitely find it some time today and post it for you. I wish you had posted this before you spent all that money on the pumps. There's also some information on the MKIV archives.

I hope this at least helps a little and like I said I will find the information for you and post it for you.

Hey off topic a bit. I'm about to move to Bowie and I think you and a few other guys are in that area. Hopefully I will be able to hook up when I arrive.

Tony, it sounds like its the steering rack to me. There are'nt too many parts in the power steering, and you have already replaced the pump (3x). That would be my best guess. Unelss you just have a ton of air in it...
Good luck.

have you checked PPS solenoid connection by the steering rack(driver's side)? If it's secure then have you checked the PPS ECU connection?

I found the info I was looking for. It's about issue concerning the speed sensors and how the signal gets to the ecu. Anyway I'm pasting what I found on the MKIV archives, hope this helps.

The issue being if the signal is not reaching the ecu then it does not know how fast the car is going and does not adjust the speed sensing steering correctly.

Tony,

Also check the vacuum lines attached to the power steering pump solenoid.

One vacuum line is routed to the intake manifold and the other is routed to the throttle body.
