96 ranger wont start

[hulkjr]

manual trans 96 ranger 3.0 v6 wont start codes P0303 P0172 P0174. Will these cause a no start? It turns over fine. Replaced injector #3 about a month ago, and spark plugs. Any ideas?

303 is misfire in cylinder 3, injector 3 a junkyard,reman, aftermarket, motorcraft??
I only know that one off the top of my head because the taurus in the family herd just threw it as well.

The other 2 codes are rich bank 1 and lean bank 2. None of which should cause a no start on their own. Whatever is causing the codes may also be causing the no start.

has not done it again until today, gonna change fuel filter today, May change out fuel pump in tank . Any ideas why not letting fuel in to start?
