So the engine ran awesome for the last little while then I could feel a slight surge which got worse over the last 2 weeks. Now it’s so bad it won’t start. It will run for a second and that’s it. Lots of smoke. It has new pmd, injectors, ip, timing chain and gears, all sensors are new except boost, new fuel filter and lift pump. No codes present. Checked for air on fuel line at ip inlet. No air. I’m stumped and so angry I want to sell the pos!! Please help
