I'd be really interested to know what voltage the ECU was seeing on
the Temp-II input (engine internal temp).  If you check before the
day warms up after an overnight sit it ought to be very similar to
the Temp-I input (AFM air temp).  If it's considerably lower the ECU
would have the false impression of a warm engine.  That could be the
result of a shorted sender, but a poor connection to the internal
pull-up resistor inside the ECU would perhaps be a more likely cause.

This could be one of those times when a trial swap of a known-good
ECU could come in very handy.

Yours,
David
