Hi All! I'm converting the power steering on my autocross car to EHPS using an MR2 Spyder pump. I found lots of useful information in this community, thanks!
I have it all wired up and plumbed, but when I went to start it, it wouldn't run. I have it wired per this diagram, except VSS is open. From what I read, the VSS is optional. I've already checked and double checked my wiring. I have 12 Volts to all the required pins with the switch on and my relay is working.
It's an eBay pump, so I suppose it could be bad. I just wanted to double check on the need to connect to the VSS.

Did you ever get this sorted? Having the same issue, my relay kicks, internal pump relay kicks, pump kicks the power relay, no spinny. New and old pump did this, I suspect a large resistance from a connection on the power wire. Will try direct from battery instead of through relay or a different relay.
