I have a 99E F-250 SD with a 7.3 225,000 miles that I am working on. I took over this project after the last owner let it sit for over 4 months. When I started working on it he had put the wrong pedestal, up pipes on it and then just let it sit. Sense I purchased it I have installed the correct up-pipes, new 99E pedestal and put everything back together. I started it after priming the fuel system and it's now running very rough, surging and sounds like the worst case of rod knock ever. Sense the first start I have replaced the ICP, IPR, CPS, fuel filter and cleaned the screens in the tank. I also checked the valve cover plugs, made sure injectors were firing with the buzz test and visually with oil pouring out and still can not get this thing running correctly. Being new to the diesel world and checking everything I found thru forums and videos can someone point me in the right direction as what to do next or what else I can check?
