Bob,

I think you'll find that the connection between the OBC and the ECU has
a broken connection. One signal that sounds like its missing is the fuel
input. The OBC uses an injector signal to measure the fuel usage (the
time the injectors are open for). If this signal was not getting to the OBC
the fuel consumption, range figures would be zero. Don't quite know how
you go about tracing the open circuit though :(

good luck,
Scott
