Hi, I just acquired a 1980 BOLENS G 194 - ISEKI TS 1910LF, it had been sitting for 5 years in the weather. The motor turns over, I replaced Oil, oil filter, and Diesel fuel, fuel filter, Glowplug lites up, two red dash lights lite up, ... air valve open, but it will not start. What should I be checking out now...??? Any Help is appreciated, I have no experience with Diesel Engines.
I do not have fuel to the Injectors, I have fuel up to the bleed screw, it is barely spitting a little fuel to injector tube. Is there anything else I can do, but replace fuel pump. The engine will run on Starter Fluid, sprayed in by removing Air Filter tube, at air valve,... Is there anything on the fuel pump that is rebuildable ... such as a diaphragm, I added some oil to the fuel pump, opened screw to let air out, no fuel to speak of past that point. Any suggestions appreciated.
Hey Dan, which bleed screw are you referring to? There's a bleed screw on the side of the injector pump. Some people mistake the screw on the filter/sediment bowl as the bleed screw. If you did bleed at the pump, try removing the injector line one at a time, in other words, remove one, make sure it's clear, then replace, then remove the next one, and so on. Diesel will form a algae that will clog filters and cake lines when the machine isn't used often. There's also a fuel additive called "Sea Foam" that is good to clean out fuel systems. I've used the stuff with outstanding results.
Is there any repair to this fuel pump? I cannot get fuel thru it... I have taken tubes off going to injector(s) ...no fuel to the tube. The bleed screw I am speaking of is just above the removable plate, in the attached picture, at the 11o position, with lock nut on it. I did replace fuel filter, and I do have fuel to this bleed screw, but can not get fuel flow to injectors. Any suggestions are appreciated.
I have also found it helpful to give the system a little positive pressure. I will put the tip of my compressors air gun in the tank fill hole and seal it with a rag and crank the engine after a few seconds of pressurizing. Generally has done the trick when trying to get things flowing.
