Question about 2002 Chevrolet S-10
When you first turn the key on, listen for the fuel pump to kick on. You might need someone at the fuel pump to listen for it. Any fuel injected vehicle when you first turn on the key the ECM or PCM will turn the pump on for 2-5 seconds to prime and build up the fuel pressure. If it fails to kick on then you might want to check for dual fuel pump relays. The priming relay could be bad, or there is no signal sent to turn on the pump to prime the system. I don't want to point a finger at the Idle Air Control, but its possible there is some gunk in it, in which just remove it by either a large wrench or by removing the hold down bolts and spraying carb cleaner over the needle and in the throttle body. I'm sure you've already tried holding the throttle down upon starting the truck, if so and its still hard to start then check and make sure the system is being primed. Another way to check it, is start the truck and pull the fuel pump fuese until it dies. Then attach the fuel pressure gauge which should read zero pounds. Then turn the key on and see if the gauge goes up, it should be over 40 psi. If it doesn't, then turn the key on and off a few times to see if it does, making sure you wait at least 2 seconds when you turn the key on to give the pump time to work. I have a 91 Isuzu Rodeo that uses 2 fuel pump relays, it was factory built with a 3.1 Chevy engine. Leave a comment to let me know what you find, and if it doesn't work then I'll think of another possible cause. And use a volt meter on the batter to verify 12.6 volts before starting, preferably nothing under 11.5 when cranking, but 10 volts is the bottom limit, and above or about 14 volts when the engine is idling.

There is not a chock on a Fuel Injected System. I am going to place questions for this on two things possible, Dying battery, Clogged Fuel Filter. Fuel Filters should be changed yearly or 20,000 miles. Its a mazing how dirty Gasoline is these days since there is no Quality regulation.

May be the choke isnt working?
or fuel is bleeding back through the line hence it takes a bit of cranking to get the fuel to the cylinders again

I just had a hard to start problem that progressed to a no start. It seems there is a factory notification about moisture in the distributor when the vent screens get clogged. After testing all the components of the fuel and all the sensors checking good and had good fuel pressure, I gave up and to it to the garage my brother uses. Guess what, it was water in the distributor that causes corrosion to build up and gives a hard to start no start condition even though it had spark at the plugs. Remove the screens in the distributor clean and dry and use a new cap and rotor. Starts up every time.
