It's interesting you said it fired with starter fluid. Really is looking like wiring/sensor issue. I would still do all the basic tests mentioned above, but I would also pull up ISTA's or TIS detailed wiring schematics for the cam sensors and trace each wire back to the ECU for all four sensors, making sure nothing is mixed up.

Also I mentioned before, do you remember if you had the wiring harnesses for the injectors bolted firmly to the valve covers when you tested? A couple of those bolts on each side are the grounding points for the injectors. Wouldn't explain the timing codes but it's possible you might have multiple issues here.

Last thing: Check the vanos solenoids wiring. I remember that being super easy to get mixed up as they sat right next to each other.
