in my experience a smallblock with good compression, the proper spark advance, a strong spark, and a decent amount of air will mostly start with nearly any amount of fuel you throw at it.
if it's not starting at all, something fundamental must be wrong.
even with half your sensors disconnected, every constant in the ECM wrong, and in total limp mode it should at least be trying to start.
datalog without the engine running and make sure things like the tps and coolant temp sensor look right, though.
open the throttle plates 1/4 of the way, and spray some fuel in there. any fuel. gas, lighter fluid, whatever burns. keep your face out of the way. what happens?
you need to go back to basics
