First I suggest that you have a code check done Most large parts outlets will do this for free.Control module problems will usually set a code. Just offhand, I'd check the egr valve to make sure the valve is clean and properly opening/closing. If the inspection readings were close but not perfect, sometimes "cheating" a bit by adding 2-3 oz of acetone per 10 gal. of fuel will clean it up a bit. It will not harm the system in that concetration,and will also clean the injector.

By "throttle body carb" I am assuming you to mean that the engine is equipped with Throttle Body Injection (TBI). The O2 sensors on that engine do not even start working for about 5 minutes. They are not going to cause a problem on start-up. A fuel filter will most likely not cause a problem on start-up or idle either. A fuel filter is most likely to cause problems on acceleration or when pulling a hill. A more likely cause would be a n Engine Coolant Temperature (ECT) sensor. If one of these is reading too low, it will cause the engine to flood and smoke black out the exhaust - especially on start-up. (LIke a choke sticking on an old carbureted engine.) If your truck is equipped with a gauge, there may be 2 Coolant sensors. One for the gauge and one for the computer. If you replace it, make sure you are replacing the sensor for the computer.

If you can jump start it and it stays running....I am assuming that you connect the Jumper Cable Ground to something other than your battery. If so, Your negative battery cable is suspect. Check both ends for ANY corrosion or loose connections.
