you're likely not starting because those codes cut off the injector (you didn't specify which cylinder(s)). If its more than one, I'm gunna doubt you'd get it to start. Usually it will start with 4 of 5 working...

According to volvo when the 1-x-5 (where x is whatever cylinder) is set these are the possible sources:

signal lead shorted to ground/supply
open circuit (broken wire somewhere, or ground not connected)
Rust in connections
Faulty injector.

I assume there's more than one code, which would rule out injectors. If its just one, it might be worthwhile to swap that one with another cylinders and see if the code moves with it... Otherwise start looking at wires and connections between the injectors and the ECU...

Buzzing isn't a good thing, just leads me to believe you have electrical problems (something is shorted or open around the ECU that shouldn't be...)

Did you make sure all the grounds were attached?

If you're not driving it "like its stolen," are you really driving?
