if the cam signal is lost while engine is running, the fuel injection system will swithc to calculated fuel injection mode based on the last fuel injection pulse, and the engine will continue to run"
from my searches people were saying to check the CAS as a source of problem for not having spark but what I am reading seems to contradict what others are saying. anyone know anything about it?
thanks

a faulty CRANKSHAFT position sensor (CKP) will definitly cause a no spark condition.
have you checked for power at the ignition coil?
