I did not use my Jinma 254 for nearly a year. I may have several problems like bad fuel, plugged fuel lines, flooding?? Starter runs OK and Glow plugs seem to work but engine will not fire even with starting fluid. I expect I will have to check fuel line to filter, then filter, then each of the Glow plugs, then each injector. Does anyone have a different routine to get it started? It was working great last time I turned it off.
