power steering help needed
I have finally got my car on the road after almost a year of working on the suspension and brakes. My power steering is not working. How Can I tell if its the pump or the control Valve? I don't want to just start buying parts and replacing everything. I do have fluid in the pump!
Thanks for any replies.

If you have a way to plumb in a pressure gauge you could see if the pump has pressure. It may "pump" just turning it over, but may not be building pressure. If I was in your shoes, I would just give up on the original system and change to the "Jeep box" from Corvette Steering. Get a new pump and be done with it.

The cylinder can't really be the problem unless it is binding up due to a bent piston rod, etc. I agree that you should be able to plumb a pressure gauge in the system to see if the pump is generating pressure. Of course, you will have to turn the wheel to one side or the other for the pump to build max. pressure. The most likely prospects are: 1) low on fluid; 2) control valve needs to be rebuilt. {I just redid mine. The only thing you have to be careful of is being sure of the order of parts for reassembly.}

P.S. If the control valve is not working properly, it will not "call" for increased pressure from the pump...so a pressure gauge alone will not help you detect which is the problem.

I am looking at excessive play in my pscv, everything else is new or rebuilt.
Had it on the rack Saturday and mechanic pointed out slop where the ball of the pscv sits in the unit (side to side)
Anyone have a link to good way to test or rebuild these?

One type of pump failure is for the driveshaft to break inside the pump. The belt and pulley will keep the driveshaft in place but the spinning pulley and driveshaft won't be doing anything. Remove the belt from the pump pulley. There should be about 1/8 inch of in-out play of the pulley/driveshaft with the belt removed. If the driveshaft is broken, the pulley and what remains of the driveshaft can be pulled right out of the pump and the pump needs to be replaced.

Thanks for all of the replies, The car only has 49,000 mile on it, but it sat for a while. I will check the pump as Jim stated , then I guess I'll just get a rebuild kit.
