Re: Peculiar starting problem

[16V JASON <jason@scirocco.org>]

Michael,
	That sounds just like Vapor Lock-- and it's usually caused by a bad Fuel
Pressure Accumulator.  What happens when the accumulator goes is that the
fuel pressure in the lines drops within a couple minutes of the car being
turned off.  Then, the fuel in the line (which is hot by the engine
compartment) evaporates and creates vapor lock, a situation where the fuel
cannot be pumped effectively through the system.  Once the engine cools
down completely, the fuel re-condenses and all is well.
	This happened on an Audi that I had for a while-- it would absolutely not
start unless it was started within about  5 mins of being used, or more
than 3 hours.
