You have spent far to much money and received far to little in return. (1)
Pick up a Bentley manual and research the various systems in your new westy.
Bentley outlines a battery of test that can be performed at home, with
inexpensive tools, that will allow you to diagnose most anything that might
arise. (2) Find a local mechanic who regularly works on waterboxers.   If
you rely on the dealer for diagnostics and repair, you will quickly be cured
of any desire to own a vanagon.
Some folks mentioned fouled gas, check for this by removing the fuel line
coming from the tank to the filter/fuel pump. Drain a good measure of fuel
into a clear container and check for water /rust. If the fuel is
contaminated tank removal is not that big a deal. I did mine last week,
removed/rinsed/installed in an afternoon. If fuel is clean it is obviously
something else. From what you describe I would suspect fuel pressure
regulator. If you need help with anything feel free to contact me.  Good
luck,  Jim 83.5 westy.
