Borrowed another CAS an ignitor from trozzle this morning, still no kick with them on.
Pulled the cas off with the ignition on and turned it by hand manually, injectors fired but no spark, moved the sensor around and i got spark and fuel, move the sensor again and back to just injectors.
So i have a break in one of the wires for the CAS, will look at trying to find which wire is causing issues and see if that gets it going again.
