i fugured it was normal for a truck that didnt move for 2 years and now
i am getting a lot of black smoke at acceleration. idles fine with no smeke when i
accelerate it gives off black smoke. i have chacked everything i can think off
injectors were pulled out tested all good. new fuel air oil filters everything was changed
turbo is new. i looked for boost leaks everything is good. the EGR is clean. it also has low power it and the only thing i can think of that i didnt change is the injector pump. if any one could help me out i would be really thankfull i know that this truck is not very popular and there are not many out there. is almost impossible to fund someone who knows about this engine, thank you

Thank you very much for your help after going over everything again I still have the same issues and I managed to find a used injector pump. There are 2 pressure sensors located on the top of the pump. I was woundering if I should just swich the 2 sensors or vhange the entire I jector pump. The truck starts without any problems. And runs perfect at idle. When driving it has a slight misfire and with full throttle it still smokes black smoke a lot
