Yeah slow down a little man. You have 2 posts on here and both ask the same question.
As mentioned above what year is it? Not that it should matter cause from what I am reading here, 12 is the same for the 4 and 6cyls. Also what lead you to change the injectors, fuel pump, and fuel filter? Was this in response to the code 12 or was this unrelated maintenance? According the FSM that can be downloaded from the "Sticky" at the top of the Classic's Threads, 12 would not be related to fuel.
Anyway, lots of knowledge here and I'm sure you'll get some help but a wise person once stated to go this route: Story, Problem and Question. :biggrin2:
