"EURO" Shop Couldn't Fix it...in a YEAR?? (Saab Injector MISFIRE)

Another Saab V6 TURBO!
This one starts up and runs...but only on 5 CYLINDERS...
Code P0203 - Injector 3 Circuit Fault.
How hard can this be to diagnose?
Well a "Specialty Euro" shop couldn't figure it out in a YEAR!!!
Customer got fed up and towed it to PHAD from over 3 hours away.
Let's dive in and FOLLOW THE DATA.
Will any parts be required?
