Jerry, really this problem would have shown up if you just did the ECU
plug tests per the Bentley Manual.  One of these tests is for ECU
power.  Always start with the ECU plug test and go from there.  It takes
15 minutes and an ohm meter to do.  Everyone skips it and jumps right to
the expensive stuff.  I have fixed so many Vanagons that other shops
couldn't just by doing this simple test and finding the problem quickly
and easily.
