Car won't start cold
So after a couple of cloudy coldish days my car wouldn't start at all. Today the sun is out and a bit warmer and it started right up. Can anyone tell me what might be the problem here? I found one instance online where someone said his PCM was disfunctional and had to be replaced and wouldn't allow his car to start cold. He said if it's brought in overnight and prevented from getting cold and then the car starts up cold this is a sure sign. Any ideas about this? I really need some help here,guys. This is my only form of transportation and I am driving 30 miles daily for school. I need a fix!
