Here is a pic of my emergency fix of the Hall Sender connector on the exterior of the dist.
Got me home safe and sound.
Swapped in a dist. with a good connection and it is still going strong.

Hi Ken,
The Hall sensor definitely has potential to be a culprit here, as a
no-start condition required that it be removed and reattached while at
EveryBus just after I picked up the vanagon. Since that time the
external connector has been held to the distributor with a sturdy cable
tie, and everything has been fine. I checked it yesterday, it remains
dry and well anchored.
I have a complete spare engine, but it's a 1.9 and the hall sensor has a
completely different connector, so it's not the easy swap I thought it
would be. My franken-engine is a 1.9 block using 2.1FI and cooling.
I guess I'll add a replacement hall sensor kit to the ASAP tune-up list
and keep my eyes open for a spare ECU locally. But if things suddenly go
south and I need one in a hurry I certainly appreciate knowing where I
can get one when I need it.
Happy Trails,
Greg Potts
