That doesnt make sense.....
On my c220, the alarm diables the starter completely. You turn the key and nothing. If it is in start block mode, it should not crank and try to come to life, it would just sit there, and the starter wouldnt crank at all.
I believe the immobilizer in these cars is starter interrupt, NOT fuel pump interrupt.
Why would they design a system, where the there is the potential for the engine to start (with the fuel already in the lines) and then stall out because its run dry of gas?
I dont think your problem has to do with the security system. It either has to do with the ignition or fuel delivery systems in the car.
Hope this helps
