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

What is your question?

It will start if it has been in the garage or if it's above 32 degrees. I was told to replace the coolant temp sensor because when they go bad they read -40 degrees & dump to much fuel into the motor causing it to flood. What else could be the issue causing it to not start. 92 caprice wagon 5.0L
