This is a Chrysler system and it's very effective and reliable. The idea is if a fuel line is ruptured in a crash, the engine can't run without fuel pressure, so it stalls. When the Engine Computer stops receiving pulses from the crankshaft position sensor and / or camshaft position sensor, it knows the engine has stopped rotating so it turns off the automatic shutdown relay, (Chrysler), or fuel pump relay. That turns off the fuel pump so it doesn't dump raw fuel on the ground creating a fire hazard.
