The first thing that jumps out is the mix between fuel and spark issues. It sounds like you got fuel under control and spark is now unreliable.
We are not talking misfires... instead no firing!
Use a good scanner to report all faults to help figure why your ECU is cutting off.

Are you positive no spark is the issue or is it your fuel delivery?
What's your fuel pressure?
How do sparkplugs look like?

More arguments could be made.There is really little chance of diagnosis with these sad tests.But without diagnosis, knowledge, or time...How much does it cost to test that?
It saved me once from getting into diagnosis with diagnostic machines and oscilloscopes and wasting time. Therefore, your statement cannot be confirmed"You cannot disconnect these two sensors and expect that to help the ECU turn on."
It is clear that disconnecting both at the same time would be counterproductive.Even so, I insist, just as you want to do, that a diagnosis in this part of the story would be the only correct option.
