What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Obtain a proper fuel-pressure measurement with the correct equipment and specification before replacing the regulator or another pump.

The pump is good, brand new part, but vehicle not getting fuel and still will not start still

Discussion summary
car will not start
A vehicle stopped while driving and would not restart. Fuel delivery became the focus, but replacing the pump did not restore starting. The owner eventually clarified that fuel pressure had not actually been measured and had ordered a regulator.
Reported outcome: The no-start remained unresolved.
Statements that power reached the pump did not include loaded measurements. Fuel observed in a line was not a quantified pressure test.
