You'd need to implement something to let it know that the engine had been run just a moment a go. For example MOB, you turn round turn of IGN to pick up MOB but with ign ON the engine wont start until fans have run for 5 mins lol...
I would say that a sensor to detect explosive vapours before allowing the engine to start may be a better bet... They do exist I see.
Damn! That's probably the reason why it's not in common use and lack of forethought is also the reason I'm not a millionaire!
