List,
I'm a bit confused. It seems that there are two schools of thought, when it
comes to runaways. One seems to say that runaways are due to an inability to
regulate the delivery of fuel, through the injectors. The other says that a
runaway is caused by the engine sucking lubricating oil from the sump,
through the turbo, and into the intake, thus providing an excess supply of
combustible "fuel" to the engine. There was even mention of excess fuel
being provided by an external source, such as a leaking natural gas
pipeline. Is a there a single cause? Is everybody correct? Is there an
expert out there (Andreas?) who could address this question. No offense to
the member who is an ASE certified mechanic, just wondering if there is a
definitive answer to the question.

Would a 1/4 turn shutoff valve, in series with the fuel inlet to the
injection pump afford any runaway protection? As close as possible
to the pump.
Would there still be to much fuel in the pump before the engine
destroys itself? Pump would be sucking a vacuum at this point.
Assume here that there is a cable attached to this valve that
you can get at on the dash when this happens.
