It may not be as surprising as you might think.

The fuel pressure relay activation is considered part of a safety critical circuit. In the event of an accident, that relay is supposed to be disabled to prevent fuel from being sprayed around & creating a fire hazard. Safety critical software is typically compartmentalized & isolated from the rest of the operating system. The ignition & starter would not be considered safety critical.

That does bring to mind a surprising thought though (surprising because I thought of it). What is the sensor that shuts down the fuel system in the event of an accident & could that be his culpret?
