I noticed in your post you mentioned you were new to 4 wheeled vehicles (I'm assuming this means you've ridden motorcycles exclusively until now). Not sure if you're aware, but your truck needs to have the accelerator pushed all the way to the floor at least twice when starting it cold.

This accomplishes two tasks simultaneously :
1. Primes the carb with two shots of gas from the accelerator pump.
2. Allows the choke to set into the cold position.

On my old '81, there are times when it's really cold outside I'll have to stab the gas pedal at least 5 times to prime it enough to get it going. And that's with the electric fuel pump having run for 5-10 seconds first. My carb (and the original one did too) allows all the gas to drain back to the tank after it sits for a while. So without the electric fuel pump, it would take FOREVER to suck gas all the way from the tank and refill the carb bowl.
