Does the tach jump while cranking? It should.
How did you measure power (lack of power) at the injectors? The injectors are supposed to get battery voltage constantly. The ECU fires them by closing the ground side of their circuit.
But FIRST... You say you've got low voltage while cranking. I'd fix that first, because maybe that's the real culprit. Corrosion at ANY of the battery cable connections? Both ends of those cables!
What's this about AC voltage? Does Bently want you to measure an ac ripple? Measure DC voltage across the actual battery posts while cranking. If THAT drops to 3.5v you've got a bad battery.
