Important edit before you read this thread-
It had nothing to do with the immobiliser.


My car lives outside and is subject to a lot of condensation. I went out to use it yesterday and it will start but not run. Clearly a problem with the immobiliser circuitry. (Subsequently- AA diagnostics said it is an immobiliser problem but we suspect the cam sensor) Depressing the clutch pedal (some cars have switches) and replacing the key fob battery (the detector ring on the ignition switch shouldn't need it) have no effect.
I'm now running a fan heater and dehumidifier in the car in the hope that whatever is damp and shorted will dry out and unshort.
I've read a lot of forums on "deleting" the immobiliser- anyone on here have any advice please?
