Well Chris,
Your Hypotheses are the same as I would have offered. If it's flooding,
you can floor the accelerator with the key off, then still holding it
down, crank the engine for ten seconds. This dries out the flooded
cylinders as the "brain" senses the floored accelerator and shuts off
the injectors. Don't crank for more than 14-15 seconds, it's not good
for the starter.
Another thought is that your injectors are dirtier than hell, (this
could lead to flooding as the gasoline would be injected but un-burnable.)
I would get a can of injector cleaner, the kind that is pressurized and
hooks up to the fuel rail and you run the engine off of it, not the cheap
stuff that you dump in the tank, but if your budget says go with the cheap
stuff, it'l help a bit. Even if dirty injectors aren't the problem,
cleaning 'em never hurts... Wait a minute, I can't think of where to attach
the cleaner can in a vanagon... Anyone know?... tell Chris.
If it's not these problems... And it is the FI brain...
I'm sorry Chris, but I can't help you... And it's gonna mean eating
navy beans for a month because your paycheck is goin straight into the van.
Cheers
