Bjorn,

It sounds like the high-pressure sensor might be the culprit.  The L-board is
the other, as you suggested.  Check on vanagon.com under "problems"...there's a
description of the dynamic oil pressure system and whether the switch should be
open or closed at good pressure.

Also, it wouldn't hurt to install a real oil pressure gauge...the analog kind.
That way you know for sure what's going on, especially on a new rebuild.
