Did you replace spark wire 1 by one,? if not bingo, you layed them down wrong.... (did car just die, by self or after a tune up?)
4.3L V6?
please stop throwing parts, you rich>? (60k tune up excepted always)
the EFI engines will not put out fuel if spark is dead.
what does getting fuel mean?
1: injectors squirt?
2: the cracked open rail plug dribbles?
what?
3;spark plug tips wet,
4: black smoke out tail. what/?
it's a no start, cranks perfect car, you keep saying no crank.
A car that can not crank and can never be started unless push started,
with a M/T STICK gear box.
ANSWER: ?
seems to me its flooding. , no>? soaking wet spark plug tips?
when EFI , floods a car , WOT cranking clears the flood.
Wide open throttle, its in you operator guide, RTM.
so if flooding, what i do us cut power to the fuel pump
the crank it dry. (black smoke out the tail, and then sputters an runs and stalls)
then, i try only test fuel. that is right,, no fuel pump power.
and make sure my engines sounds perfect with just test fuel.
if that is all true runs on test fuel,
then the problem is FUELING ONLY>
all in the span of 10mins work.
see scotty do that here.

you might try checking the catalytic converter.. it could be clogged... not letting the engine breathe like it needs to

You might try checking the timming if it is out depending on the milage you might need to replace the timing chain and guides good luck
