Well I replaced my fuel pump assembly with the Delphi unit from rock auto and also did all New NGK spark plugs and it Still just cranks and cranks in the morning.. some days it’s fine, but not lately.

what else makes the Jeep hard to start? I’m like 4-5 tries if it’s cold. Once it warms up It runs like a champ.

The mechanic thinks the throttle body maybe? But I don’t know.. I just cleaned it and it seems fine.

maybe relevant? Note: I have a vacuum
Leak somewhere too probably a bolt on the intake / exhaust manifold that I can’t reach.
