Hi all,
Long time no post. After more than 3 years of sitting in my garage
waiting to be rebuilt, my 91 turbo legacy is back together. The
engine has been totaly rebuilt and I have dropped it back in, but it
won't start!
So I dug around and tried to get the ecu to flash codes to me. Want
to see if it will tell me if a connector is not connected. In the
process I disconnected the cam sensor to make sure that I would get a
code flashed. When I finally figured out how to work it, it indeed is
flashing codes, 13 and 22. I expected 13 as I had disconnected the
sensor. I reconnected it and the code will not go away so I assume it
is stored. To test this I disconnected the crank sensor and bingo!
code 11. Now this won't go away. 11, 13, 22, 11, 13, 22... Anybody
know how to clear the ecu? I tried disconnecting the battery over
night but the codes are still there.
Meanwhile, on the won't start front, I got spark, looks like the fuel
pump is working but I can't seem to measure any voltage across the
fuel injector connectors when cranking the engine. I have the 3 big
wire connectors behind the battery connected... hmmm. I don't
remember a engine to body ground strap... hell, its been 3 years
though. Anybody got any ideas? By the way I did check the cam sensor
and it appears to be cranking out volts... seems to fluxuate
between .2 and .4 volts AC. I sure would like to clear the ecu and
see if the code comes back. Also, any advice on a recommended OBD
reader would be cool...

Rebuild won't start, fixed!
It runs now!
Turns out I screwed up the timing belt. I was aware of the notches
and arrows on the cam sprockets but I missed on the crank sprocket
and used the arrow in front instead of the notch on the crank sensor
flange. Luckly, it's pretty easy to get in there, just pop off the
cooling fans and there is plenty of room to work. Once I realigned
the belt, it fired right up. So you may see a Black 91 turbo sedan
running around Bothell, WA now!
I must say that working on this engine is pretty cool. I was somewhat
intimidated by the massive volume of hoses attached to the engine but
they all make sense, and all in all the car is pretty serviceable.
Can't wait to start putting some mods in.
By the way... for years I had a mbna Subaru credit card, and had
gathered a boatload of Subaru dollars. I used them to finance this
rebuild, as you can use them in the parts department of any dealer
which is really cool. I was dissapointed when mbna discontinued the
program a few months back but Subaru has started it up again, this
time with Chase so if you are a Subaru nut like me it really pays off
to have this card.
