I have a 1999 Ford Taurus 3.0L DOHC, the p/s pump reservior is mounted seperate on the fenderwell. It lost its power steering, I have replaced the pump and the rack, both are ford remans. I blew out the lines to make sure everything was clear and added an inline filter. I purged the system with the front wheels off the ground moving the steering left to right but still don't have power. When I shut the engine off you can still here the fluid circulating for a few seconds. I am at witts end and don't know what to do now and would appreciate any help. Thanks

Start the engine with the fuel shut off so it will run out of fuel, (pop the fuel relay out or bang the fuel inertia switch so it won't run. Then loosen the pressure line and crank the engine to see if fluid pushes out. If it does, you'll know the pump is working and the problem is with the rack. Where did you get the parts?

I got the parts from Ford dealer, both are remans. Thanks

Bert

Those should be good then. I bought a rebuilt pump from an afermarket and ended up buying another one from Ford before all was well. They can have a defect too but not as likely.

I put 2 napa pumps on first and then went to ford and got the pump and rack and filter. I really think the pump is working but I'll try what you suggested and find out for sure. Thanks

That car has V.S.P.S. controlled by the V.S.S. and computer. Are all the wires connected ? Do you have voltage at the solinoid and valve. Do you have the proper rack ? You might have to put a scan tool on it to see if the electric control side of the
rack is functioning.

There aren't any wires that go to the rack, there is a pressure switch in the high pressure line and it is connected. thanks
