I don't know of anything else that would cause it to start hard only when it is cold outside. Also the other morning when it was only 30 degrees it almost didn't start at all.
The first thing to check is your batteries. If they're not up to snuff then that's your first problem. Wait to start light on for 15 or 20 seconds isn't unusual when it's cold. I wait 15 or 20 after it goes out to start mine. The glowplugs can stay on for quite a while after the motor is running. Sounds more like injectors than glowplugs. Have you tried plugging in the block heater to see if that helps? Also, what kind of oil are you running?
