I've been working on startup for a while now. I've read and reread many threads & posts, particularly those pertaining to Ford 4.6L Modular engine. I seem to have an issue with the firing order. I started to check each cylinder per Danny's instructions, but this is where I hit the brick wall. Cylinders #3, #4, #5 & #6 are not getting a signal to fire. I did a System Log and see a good crank & cam signal. I tested them all with the same stock Ford coil pack & plug setup a couple times, even powering down the computer overnight. I searched the forum, but haven't found a similar issue. All help will be greatly appreciated. Bruce
