Newbie question, slightly off topic.

Hi people.

I have been lurking around quite a while now, and though my
own EFI project won't start seriously for another month or
two I have a related question.

The scenario is this. I installed a anti-hijack/tracking unit
in my car (Audi-EFI). The immobilizer relay (to disable the car 
in event of an hijack) is connected in series with the booster
pumps' fuse, ie when the car is immobilized the main fuel pump 
will run dry.

When this happens what damage will be caused to the engine systems?
I'm quite willing to accept an amount of damage in return for recovering
my car, and the immobilizer will only be actived with my constent,
but knowing what will break would be nice.... ;-)

Does anyone know whether the fuel pump is switched off immediately when the
engine dies of fuel starvation?
