1996 Astro van engine issue ---rehashed...

Updated.....
1996 Astro Van. cranks, good spark, good fuel, may idle, but falls on its face when throttle is touched (like it is starved for fuel). Once
you get it to actually start & idle, it idles fine & will crawl around the parking lot in gear without problems. But hit the gas, and it will gasp for fuel & stall.
If you crank it over & over, it will not start. You need to bump the key over & over to get it to start, or else it will flood. Will not start in "clear flood mode"
Replaced: --------------------- Fuel pump Fuel filter Fuel regulator Fuel Injector spider assembly Fuel pressure, tested very good Coil Electronic spark control Wires Cap & Rotor Spark plugs Firing order checked 4 times (it will idle smooth as well) ECM TPS Cam sensor MAP sensor MAF sensor EGR sensor Checked for vacuum leaks around the intake. Removed exhaust converter to check for blockage
I am at a loss of what to do next. Anything that could affect the running of this truck has been replaced (as far as I know)
On the scanner:... No OBD2 codes or faults. Everything is within parameters. No exhaust restrictions, no intake restrictions.
It sounds like I'm missing some other fuel control piece that may be the answer. Something is not telling the fuel to release above an idle.
As of now, the dealer is baffled. The only sensor that has not been changed is the Idle Air.

Check for changes in injector pulse width as the throttle is opened, I assume the fuel pressure is 60-65 under load, correct?
