I suggest an initial cheap diagnosis would be to clean the throttle body and idle control valve. If that does not work check your fuel pressure after the vehicle has been running with the engine off and see if there is any system bleed off. Your truck should fuel pressure in the lines for a while after the engine is shut off. If there is an imediate leak down your system is leaking down somewhere externally or internally such as an injector, pressure regulator, fuel pump. When your system bleeds down it may take several seconds for the system to pump back up to an acceptable operating pressure before the engine will fire up. One more thing to consider, if your injectors are not holding pressure after engine shut down that means that they are leaking excess fuel into your cylinders causing a light flooding condition which could contribute to a long cranktime after a recent vehicle operation.

The simple thing to do is to turn the key to the run position for 5 seconds to allow it to build up fuel pressure and then turn the key to start.. If this works you do have a leak down. Most likely the valve in the fuel pump is the source of the leak. If so there is no worry just continue to build up the pressure before starting.

It also might be a leaking fuel pressure regulator. I've seen them leak fuel into the vacuum line connected to it and allow it to go into your intake. An easy test depending on how accessable the regulator is, is to pull the vacuum line off with the engine running and see if it spits fuel out of it. If it does then the regulator needs to be replaced.
