Hi all,
In the off chance that anybody cares, here is what happened with the
Subaru cold start problem that I posted about here a few days back.

After having the repair place attempt to read the fault code with
their high tech snap-on scanner and getting nothing and changing the
coolant temp sensor, the problem persisted. Still not starting cold, rad
fans running, and constant "check engine" light. After pleading here for
help, and getting a few good links to Subaru code extracting procedures,
(Thanks L. Jaques!) I braved the cold yesterday and crawled under the
dash to locate the test connectors. According to the procedure, there
are 2 wires that you hook together, then turn on the key to get the
computer to flash the codes to you. I found and connected them, turned
on the key and waited. There was lots of odd relay clicking sounds, for
a few seconds, check engine light stayed on, no codes flashed to me, and
then the radiator fans shut off! Then the clicking stopped. Feeling bold
that something had changed, I turned the key. Engine cranked for a few
seconds, fired and purred!! That after a day and a half of sitting out
in below freezing weather. Check engine light went out, fans stayed off
and the idle dropped as it warmed up. Engine warmed up, rad fans cycled
as they should. Back to normal, YEAH!

Feeling a bit reserved, I did not deem it offically fixed until this
morning, after a series of cold starts last night and this morning.
Every one perfect.

Not sure excatly what happened, but am blaming the temp sensor, and
crediting a test-mode-reset of the computer as the final step. That last
part is likely BS, but I am not above making stuff up to convince my
daughter that I am brilliant (even in the face of evidance to the contrary).

Thanks again for all or your responses and ideas. This gang never lets
me down.

Much appreciated!

AL A.
