Why will my car crank but won't start?

What is your question?

Cranks but won't start, fuel filter is not clogged, replaced fuel pump & made sure it pumped (hose to a bottle) & it works. Seems to cycle fuel back into the tank as barely any fuel makes it to the fuel filter. Poured fuel into the air intake & it started & ran until is was all used up (10 seconds or so). Any ideas?

What makes this problem better or worse?

NA
