Hi there! First time poster, intermediate only knowledge of diesel engines...I bought a truck with a dump body that had a motor from a junk yard installed into it and the previous owner could not get it running due to a starter issue. I solved the starter issue and it is cranking perfectly. My final issue is that I have pressurized fuel to the filter at top of the motor but cannot get fuel to injectors. I have cracked each line at top of injectors and installed 2 new batteries and have cranked over the motor enough times to bleed out 10 engines. I tried a little bit of starter fluid and the engine is very responsive. still cannot get fuel to top of injectors. I have a 6 wire plug at top of the motor that is not plugged into anything but I looked everywhere and cannot find where it goes. So wondering about that as well. Also there are 2 small rubber hoses connected at the bottom of the filter housing, I do not know what they are for or go to but could they be switched and hinder the fuel flow? Welcome any thoughts and thanks for help in advance.
