My first guess would be to check your engine coolant temperature sensor (ECT) and then the fuel system. Lacking any diagnostic data it's really hard to just make a guess.
Sure go ahead and listen to everyone who says check the carb. They must not realize that this truck has a Vortec and that all Vortecs are injected. They must also not know that the ECT if defective often prevents an engine from starting if it's OBD II compliant.
Realistically you should either spend the time to get educated on how to diagnose the system, spend the money to get a diagnostic computer that gives you a live data stream (you'll know what that is after you're educated) OR just take it to somebody who has the knowledge and equipment to repair it. It's going to cost you no matter what you do. Throw parts at the problem just to see if it fixes it and THEN have to take it to a mechanic after being without it for so long, or just take it to a tech now and have them fix it and go on you're merry way.

there's a heating thing you can buy at the auto parts store . You put it in your engine oil hole and it keeps the oil warm during the cold. You have to plug it into electric. I used to use it for my MG during the winter months. Take it out before you crank it but when you come in for the night or whatever plug it in and stick it back in the hole. Should start right up.

ignore these other gooses above.
its a fuel problem. does the choke or cold start injector work properly?, get this checked try giving it a squirt of aerostart down the throats before you crank. if it leaps into life then thats the issue.

Go to Advance Auto, etc. and have them check your cold cranking amps; they will usually do it for free. Batteries seem to only be lasting 2-3 years now, instead of 5-7!

in cold temperatures, your BATTERY can lose up to 50 % or more of it's cranking power. Check the battery to see if it needs replacing, or just charging==probably does need replacing.
