"I have herd that the ECU can have solder connections the break (as can
most automotive computers).  If you still have the ECU and are good with
a soldering iron and have a good magnifier, might be worth a shot to see
if the problem with the old ECU can be found."

Hey William,

I tried this.  A buddy of mine who has a lot of experience soldering with
circuit boards helped me out.  We couldn't find any bad connections, but
re-soldered all of them anyway.  This leads me to believe that some
component of the ECU failed, not just a bad connection.
