Does the Van Crank over?
Have you checked the IGN Relays? 1,2,and 3?
How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.
SOURCE: My 2000 S10 with the 4.3l vortec is hard to start.
Key on engine off pressure on your truck should be 60-66lbs. A fuel pump replacement is definitely in order, bad thing is it is a whole assembly.

The plenum shouldn't be damp with gas. Is it a throttle body fuel injection system?
Could be a leaky injector.

Pull the vac hose going to fuel pressure regulator and see if it has fuel in it. If it does replace it. Just fixed one with multiple misfire codes.
