Rebuild won't start, reset ecu?
Posted: Tue Nov 12, 2002 3:03 am
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...
