I have a 1986 Vanagon GL (well, actually, 3 1986 Vanagon GLs but one
is for parts now) that won't start.  I drove onto our driveway about
two weeks ago, turned off the ignition, and it hasn't started since.
I've replaced the starter and fuel pump (they were pretty old anyway)
but that didn't make any apparent difference.  I've loosened and
cleaned all of the grounds that I could find.  All of the fuses seem
ok.  I've checked the things you can check at the ECU (temperature
coolant sensor, etc.) and everything checked out ok.  Spark plug
wires, distributor rotor, coil all pass the multimeter tests.

Wierd clue: the "buzzer" that goes on when the key is in the ignition
and a door is open (actually, none of mine buzz, they all play
something that sounds like the start of "La Cucuracha") makes a noise
like the engine turning over when I try to start the Van (by turning
the key past "on").

Any suggestions???  Thanks all.
