How about PASSLOCK, the known Chevy curse that drives some owners nuts.
|
If it's the passlock system there should be a key or lock symbol (can't rememeber which ) flashing on the dash. Not only that, I don't thick a passlock will shut it down when running, just prevent it from starting.

I don't have a fuel pressure gauge but it seems comparable to my other cars.

Get one, you can't tell from the spray coming out of the valve.

I put a screwdriver in a random plug wire and it tossed a large bright "WHITE" spark

.
Not a real accurate test but it pretty much confirms the ignition is fine, provided it's occuring at the correct time. I'm not 100% sure but I
think Passlock disables the ignition when starting so you
might have confirmed no prob with that, again not really positive.

Instantly shut right down with no restart

They are an interference engine, (that's why I changed my daughters right after she bought it). I can't remember what the recommended interval is 70K?. If the timing belt jumped, and that's what I'm leaning toward, you might have lucked out in that nothing was bend but it's a long shot.

I pried back the top of the cover ad verified that the usual suspect (timing belt) wasn't broken
|
All you confirmed is that he belt never broke, it could be worn enough or the adjuster could have went south and it jumped. Only way to tell definitively is to pull the valve cover, line up the crank/cam marks and see where everything is.

I don't think starting fluid alone will even light off....

It will, use it sparingly, it's not good for any engine, I'll only use it as a very absolute last resort on my diesel tractor. It washes the oil off the cylinder walls, ignites very easily so not necessarily at the right time in the cycle. I've used it once on my tractor when it was -20C and the noises coming out of that poor engine made me cringe,....Mike
