WILL NOT START IN COLD WEATHER BELOW 40 DEGREES

1940 Chevrolet Astro

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?

Find the fuel pump relay in the underhood power center, see if the relay is working b4 you condemn the pump
