Well, in order to add the a/c I depowered my steering rack, because I had the Miata p/s pump in the stock a/c compressor location. Now I don't like the steering feel, so I'm adding a Volvo electric p/s pump. I'm planning to put in a switch so that I can turn it off if I want.

I will look forward to details of your Volvo EPS pump install. I am considering one for MonZora, as I don't like the idea of putting manual steering input torque through an aluminum I-shaft.
I don't know how I never found this thread before, but I love it!
This is giving me ideas, even though I don't have time, money or space for another project.

Also following for future proofing!
I'm pretty curious myself! I'll be sure to let you know how it works. I also considered trying the pump from a Mazda 3 as they are easier to find, but I couldn't find anyone who seemed to have made one work.
Just fyi -I used a mini cooper pump in my Porsche ls conversion .It has been flawless for 3 years - easy to obtain and rebuild if ever needed .The Volvo pump is not .
Not a great picture - the other advantage of the mini pump is the tank can be remote mounted .Helps with placement .It might just be bad luck but I went thru an MR 2 pump and 2 volvo pumps before this .The MR2 flat failed and the Volvo pumps developed excessive noise .

Good to know! I already have 2 Volvo pumps, so I'll give them a try, but I'll keep the Mini in mind just in case!
A/C blows cold!! After fixing 2 leaks that were my fault, it turned out to be a defective fitting that wasn't my fault! Waisted some R134, but it's all good now!
Volvo pump is installed! Just need to organize the hoses and wires and fill with fluid.
I pressure test the AC with shop air before introducing refrigerant.

It held a vacuum overnight, so I thought I was good. Ya live and learn!

I have done a volvo pump and it works well.
I wired the volvo pump so that it did not start while the starter was engaged. It does have a delay of about 5 seconds, but this guaranties that the battery is not overloaded.
I did not use the mini pump because it fired as soon as it saw power. No way to control and no internet explanation or adoption.
I did not use the Mazda pump because there is no wiring info or tips to work around the Can bus requirement.
I am still thinking of PS on the Molvo, but it will be either the Volvo pump because I know how easy it is, or I will go for electric motor under the dash.
don't know what mini pump you used but mine has 7 second delay from ignition on to run .
The Volvo pump has about a 3 second delay, but I do have it on a switch on the dash to allow me to turn it off if I want. For what it's worth, the Volvo pump says FoMoCo on it! I was wondering how similar it is to the one used in a Focus.

I wasn't trying to correct you, I just missed where you said the Volvo pump has a delay!
I'm scratching my head today!! Took it out to test the P/S , brought it in to top off the fluid, and after topping it off it wouldn't stay running. Starts runs for 5-10 seconds and shuts off. Won't restart immediately, but if I wait 20 seconds or so, it will start and run for 5-10 and cut off. It did this when I first built it and it turned out to be a ground. Checked that ground and it didn't help. The second time this happened , I walked away from it for 2 days and it fixed itself! I jumped the fuel pump relay to see if it was shutting off the fuel. It started but did the same thing, pimp ran the whole time. I'm at a loss for things to check!!
Are you getting power to the pump the whole time, even when it shuts off?
Might be a clogged fuel filter . Testing fuel pressure at the fuel rail might provide some clues .
In reply to jfryjfry :
Yes, I jumpered the relay and the pump ran the whole time during and after it shut down.
In reply to dave215 :
I need to check that. I have a pressure gauge on the fuel rail, but I need a second set of eyes to see what it does when it's running / cuts off. I thought about the filter , but it did this when everything was new then went away for a year happened again, then went away for 2. I've "fixed" this twice before but really don't know how!
working alone has it's challenges . Can you run a jumper to the starter solenoid and start from the engine compartment ?
I can, but it needs to charge from all the starting attempts I've made. I'll try again tomorrow. Who knows, maybe it will fix itself again!
Good news and Bad news! Good News ... it fixed itself again! Bad News... I have no idea why! WTF!!!
