Have you checked compression?
You did a leak down, checked cranking compression, or both? Is the plug wetting with fuel? Does a noid light flash on that injector connector?I did a leak down compression check and no blow by in valves or rings i lapped the valves when i did the rebuild.
That makes me think it's a compression issue, you can burn a little and make soot but not contribute to the engine running. I would check cranking compression just to cover all the bases. If you disable fuel and crank the engine does it sound like it's skipping over a cylinder or does it crank normally?Just a leak down have to order noid light. Plug not wet with fuel but blackened from being too rich
