    I have a '94 379 xhd with a 60 series in it. It was running fine then when I went to start it she would crank fine but no start. So I checked grounds, battery connections, fuses, changed timing sensors, tried donor ECM, put prolink on no codes, and checked fuel pressure. Still no start injectors won't fire. While cranking stop engine and engine fan lights blink while the fan clutch engages then disengages. Sometimes fan will do this just with key on. I'm not the best with wiring bit think it must be problem in cab and don't know where to start. Any advice? Ps I'm in the boonies but have mechanic coming tomorrow to give it a try. Thanks in advance.

    Will it start on ether? If not, your engine's tired. Mine did the same thing. One day, went out and it just wouldn't go.
