I know dealers who've been stumped for 14 _YEARS_.

Check the fusebox seals - the rubber gasket inside the lid and the seal
to the body.  Moisture in the fuse box can cause all manner of symptoms,
including false indication of engine overspeed to the fuel pump relay.
Also check that both clips and both hinges on the fuse box lid are OK.

This problem is _VERY_ common after heavy rain when the fuse box lid
isn't quite clipped home.  Roger Galvin left the fuse box lid off his
MB ur-quattro and the damn thing was doing wierd things for weeks -
the interior lights would suddenly come on, and then the radiator fan
suddenly woke up in Jumbo jet reverse thrust mode at 3:00am in his
garage.  Frightened the bajesus out of his wife, who thought it was
a _real_ Jumbo!

One for the brains trust - anyone know a part number for the lid gasket
separate from the lid?  Might be another 'timing belt' item, like the
coolant header tank cap.

It may well be worth giving the fusebox a thorough going over with a
hair dryer.  Pull each relay and dry its pins and socket.
