Hopefully, that will be the end of your problem. I assume that you refer
to the 2 pin connector that plugs into the side of the relay box on the
left side of the engine bay. That connector provides power to the fuel
pump all right as well as being the main power feed to the entire fuel
injection system.

You should be advised that the red wire in that connector is a known
failure area. The wire gets burned spots inside the insulation and then
things stop working. Just wiggling the wire may seem to fix it but only
for a while. All the power for the ECU, injectors, and fuel pump go
through that one smallish red wire.

The first time I saw that problem was on my friend Peter's 89 Westy
Syncro. While caravaning back from a Baja kayaking trip his engine just
died in the middle of a shoulderless highway, hundreds of miles south of
the border. Fortunately I had my Digitool. We hooked it up and
immediately saw that the ECU was not getting power. After a few minutes
with the wiring diagrams and a volt meter we determined that the power
was present on one end of that red wire but not at the other. We peeled
back the boot at the relay box end and could see a blackened spot in the
large red wire just before the connector pin. We cut out the bad spot
and spliced a short piece of wire in it's place. Good to go, to
everyone's relief.

I recently learned that the old links to Darrell Boehler, inventor of
the Digitool, no longer work. Does anyone have a way to contact him?
