A bad MAF sensor can affect the fuel pump relay not to function. Do a back probe to see if you are getting the right electrical values out of the MAF sensor. A Haynes manual will indicate what voltage you should be getting.

I had a similar problem with my S70 where I blamed the fuel pump relay and fuel pump not functing only to find out it was the MAF that was bad. I ended up with a perfectly functing extra fuel pump and relay.
