Hi there, thanks for the question.
from your description it looks like you already found air in the lines from a leak at the primer pump
if the primer was replaced and the air leak fixed
you still need to bleed the system to prevent a vapor lock issue
this will require the #1 injector to be loosed while you crank the engine or activate the electric pump
when no more bubbles come out tighten the injector and the system should be free from air.
If it continues to fail to start even though it has been fully bled, then you need to check for fuel pressure first.
depending on the pressure test results, that would tell if the in tank pump has failed or if you need to check for injector pulse operation
let me know if you need anything else thanks.
