After a complete engine rebuild I made my first attempt at starting my MF203 regular inject diesel. I was not successful. I had the injectors and injector pump rebuilt and replaced both fuel filters. The lift pump is also new. The book tells me to manually pump until fuel comes out of primary filter, then do the same for secondary filter, then the top screw on injector pump, then bottom screw on injector pump. That all worked fine and I had a good stream of fuel from each of those points. At this point I opened the line to the first injector and turned the engine over. Very little fuel came out, literally a just a few drops oozed out. Same goes for the other two injectors. How much fuel should be coming out of these lines when they >are loose? I was expecting quite a bit of spray.
I repeated the above sequence and there was quite a bit of air that came out of the top bleed screw on the injector pump. However it is now to the point that no air comes out but I am still not getting much fuel out of the lines that feeds the injectors.
Any suggestions?
