when i rebuilt my ca18det in my 200 sx the CAS (crank angle sensor) run off the cam, which by the looks of it is identical to yours was out of position,
basically i undone all the bolts to it and got my dad to turn the car over while i rotated it, the car promptly fired and it apeared that for some reason the cover that held the sensor would not allow enough movement with the bolts in to put the CAS in the correct place, pain in the arse really cos i had to file the slots in the CAS out to get more rotation,
