'03 XC90 2.5T need help with relay locations

'03 XC90 2.5T
Acquired this vehicle at auction:
Issue #1 starter rolls engine, has spark, wont fire as fuel isn't making it past injectors. Any solid pointers on where fuel injector relay(s) may be?
Issue #2 Dash has no lights at all, apparently can't run OBD scan unless dash is connected(electrically?), cant seem to nail down a relay(s) or fuses for anything other than "infotainment" ,but those are intact. I'm very good with mechanical side...but the electrical on this model is more difficult than the 240 series, IMHO
Thanks for any input, Ive already filled the swear jar...

Yes, modern cars with the multiple canbus systems is just a little more difficult!

You can find wiring diagrams for a 2005 here - they might be similar enough
