As the thread title states, the power steering on my 94 5.0 swap doesn't work. I didn't do the swap but it appears to be the factory Mazda pump.

The fluid level is good. Also no major leaks. Doesn't make any noises. The belt has tension and doesn't slip.

Searching didn't provide much useful info unfortunately so I'm at a loss. Here are some photos of the set up. I'm open to all suggestions at this point.

 

I got new ps fluid. Going to flush & refill and make sure there's no air. If that doesn't work I guess it's time for a new pump.

 

Did it ever work since you have owned it?

 

Nope i just got it. The builder said it was working 3 years ago when he sold it. After 230k miles it's due for a new pump i guess.

 

Looks like a nice setup actually!

They integrated a 6 rib pulley onto the Miata pump so pay particular attention as to how they did that. You do not want to mess that pulley up in any way otherwise you have a "project" on your hands. If they modified the pump shaft to accept that pulley you may be in trouble as well.

It could also be the rack itself too i would suppose...

Time flies... it's a 2002 Explorer v6 pump. Replaced 4 times (reman units) without success. No noise, leaks, or anything.

Someone pointed out the exhaust heat could damage rack seals. With forward facing headers, it's quite likely.

It's much easier to steer with street tires vs slicks; not a big concern now. Probably have to disassemble at some point.
