Iv had the same issue once on a truck.
It turned out to be the Map Censer.
Also sounds like fuel pump related?
You say you hear it kick on, but even
a bad fuel pump will still kick on but wont
have the correct pressure to fuel the engine.
Make sure if it do start, add fuel cleaner
and check the EGR valve. You can clean it
with carb cleaner or pure gas. Let it dry for
bit, Put it back in and try it. If all fails,
Check the wires that run through the fire
wall, because Chevy had an issue with croading
wires running through from the engine, to
fuse box computer. For Astro vans.
