Don't have the service manual in front of me right now, but there is a sequence for the ABS light when you key on. Depending on what happens there will point to your problem. So check the manual or have someone post a copy of the diagnostics page. That will help you decide where to look.
My *thoughts* are that you may have a failing pump and it may have blown the ABS fuse. Generally I think if there is any ABS fault (obviously since there is no pressure), the light should be on. The light not on makes me think blown fuse. Why would the fuse blow since replaced the accumulator and relays? Probably excessive current draw. When you last heard the pump run, did it sound happy or did it sound like it was working a bit too hard?
If it does come down to it, you can change both the pressure switch and the pump with the unit in the car. Not easy, but you can do it. The pumps can be rebuilt or there are used ones out there. I have a slew of used systems, I'm sure some of them probably have a good pump. You can test the pump by simply hotwiring it at the connector.
