When you start the truck cold, look in the neck of the radiator with the cap off. Is the water circulating already (with the engine running)? If so, no/or stuck open thermostat.
Have you ever had a carburated vehicle before? If the choke and linkages operated by it are not set right, it will act this way. And yes, not injected, you have to pump it 3-4 times BEFORE even spinning it over. No fuel, no start.
