why won't my car start when it gets below 32 degrees?

Yes I did replace it & the new updated pig tail to fit the sensor.

Scan test needed to view live data 'before' cold start!

will have to find someone with obd1 scan tool so i can have that done

Any auto repair shop should be equipped for that!.. In fact should be able to scan test with live data from 1980 1/2 to at least 2013..!
