I could use some troubleshooting advice for my 87 westy over an intermittent
starting problem, perhaps on where to start looking for a solution. Always
when cold, typically after spending a couple of weeks parked in the garage.
The engine cranks fine and I believe the plugs are firing because it sounds
like it is just about to start up, and smells like very rich exhaust while
cranking over.

Suspecting a fuel delivery problem, I checked for ignition-on fuel pump
vibration, which passed. I was planning on a fuel delivery check and then
fuel pressure check, but first decided to replace the temp II sensor with a
new spare I keep on hand. In doing so, I noticed that the leads to the
coolant temp II coolant sensor are brittle and are nearly broken right at
the point where they emerge from their plastic sheath a few inches from the
rubber connector boot. In fact, the insulation is damaged on both wires
enough to expose conductors. I need to cut back this plastic sheath enough
to expose undamaged leads for a splice, but with age the sheath has become a
tightened hard plastic enclosure - tough to cut without damaging wires
inside. 

Does anyone know of a source for a new temp II connector? I am hoping that a
new one will provide not only unscathed but longer leads, providing some
slack for a splice. Except for these rare and abrupt starting lapses, the
van starts great, idles fine, and runs smoothly when we need it to. I have
checked and cleaned all engine bay and transmission ground points that I
could find. Any help is appreciated, thanks all. -Phil
