JH7900 Report post Posted January 8, 2024 Can anyone tell me if there is supposed to be a firing order for the fuel injectors in the 3.0L Duratec engine? All 6 of my injectors all fire at the same time and that seems odd to me. See the picture. I recently rebuilt mine, cylinders 4 and 6 aren't firing and I'm trying to track down the problem.
