WILL NOT START IN COLD WEATHER BELOW 40 DEGREES

Chevy Astro Van 1997, 4.3 v6 mileage is 120,050.
Whenever the outside temperature drops to 40 or below I have to use starting fluid to start the van. Usually it will take 2 sprays, and then it will start right up, and start up again all day. Once it sits for 8 hours or overnight and the temperature drops it will not start, unless I spray it again.
Once the weather is warmer or over 50 degrees I have no problem starting the van at all. During the summer the van starts very easily.
I changed the fuel pump 2 years ago along with the fuel filter. I checked the spark and it is fine, also changed the coil wire. Could it be the fuel pump is bad again?
