AAN harness in a B2 chassis

[ralleyquattro]

Having issues with a non start... everything is connected and ECU turns on the pump and fires the spark plugs during cranking, just no start.
Tried output test to see if injectors will fire, no go. I do get +12 at S72 and the fuse is fine.
All grounds are good and only get G28 code which is normal for non running engine.

Ideas, suggestions?

Martin: Is this with an immobilizer ECU or a normal North American non-immobilizer UrS4/S6 AAN ECU? Might make a difference.

Check hall sensor.

Lots of good strong sparks at the plugs or weak sparks?
