just re-read first page

a fail AFM, doesn't stop the car from starting, it will start, just crap itself
stuffed immobiliser or wiring to it can though

did you not post up something about rewring your own immobiliser before? and had to stop mucking about with it because you were swapping over to a new unit?
and you hard wired the radar detector and interior lights went as well?
don't know if this is all related but, could it be a combo of this and the AFM that made things worst?
