Yesterday my 86 Vanagon Syncro died as I pulled away from a parking
space. It would not restart or even sound like it might. I cranked away
to no avail and checked connections etc. Then I called the Auto club for
a tow home. After a couple of hours of checking I determined that it was
flooding. The injectors seemed to spray constantly while the starter was
engaged. Finally I removed the ECU and put it into my other 86 vanagon.
The other van would then fail to start also so I put the ECU from it
into the original problem van and it started right up. I noticed that
the part numbers on the ECUs were slightly different as the good one had
a D after it. The bad one did not. Can anyone tell me the what numbers
were used in what years and what the functional differences if any might
be? Also does anyone know where to get another one for a good price? I
would be interested in a place to send my bad one for repair is such a
place exists.

TIA
