I have a 07 f150 5.4 lariet that is hard to start but when It
starts it runs like it’s new. Thought it was th fuel filter still
does it. Changed the fuel pump ( twice) still does it. Any
help would be helpful

does this happen every time or just at certain times ie. cold start , warm start , after fueling ? what do the plugs look like ? instead of a second fuel pump you could have gotten a fuel pressure tester
Right, in cases like yours I would use a fuel pressure tester first.
Have the injectors checked or search the net on how to check. One or two bad injectors could make for a hard start.
