Engine Won't cold start

Hello,
The weather in my area has recently dropped to below/close to freezing. The car has never had an issue with starting in the past, but this is my first winter with the car. The car now doesn't start when it's close to freezing outside. The car cranks, so it's not the battery or starter. I think it might something with the fuel system. Where would be a good place to start looking?

The car is a 1987 5.0

Thanks!
 
Have you checked for codes? The check engine light (CEL) will only illuminate on emissions related codes so there can be other codes stored without the CEL coming on.
