Fuel pump safety cutoff

["Rob Robinson" <FastrTime@t-three.com>]

    Many cars that came with electric fuel pumps use a relay or relays to
switch the pump on during starting and when the alternator is generating
voltage, or the oil pressure is up. This basically means that if you have a
serious crash, the electric pump will turn off when the engine stops,
whether or not the key is on.
