Just before the trip, I had a 15-minute "issue" where the vanagon would not crank.  I waited re-tried and 
it started and we travel 3-4 days without another instance of trouble.

Now, back home, I moved van on driveway and now cannot re-start?  

I have spark (blue, regular intervals, etc.).  How do I check for fuel delivery and fuel regulator issues>?

I've changed the fuel filter fairly recently and my fuel pump "sounds" OK.....

Any suggestions....
