Possible fuel pump fuse...not in a wiring schematic but it is on the side of the battery.

I would go with globalhelper on this one, because there are many possibilities here. If the ignition is not working, the fuel pump will never turn on, so your assumption may be incorrect. A few things to be aware of on this vehicle are the fuel pump relay and RPM Sensor. But the fuel pumps also fail, as do the MAF Sensors. All can cause similar symptoms. I suggest you look for a shop in your area that specializes in Volvos or European cars: http://repairpal.com/volvo-within-10-miles-of-30392
