1710 fuel problems

[Kellydwellssr]

Running great when I parked it last week. Started as normal but wasn't running right. Slow or no reaction to throttle position and just wasn't running smooth. Finally just stopped running. Seemed like it ran out of fuel. Checked but plenty in tank. Sediment bowl was dirty tho. Removed it and cleaned it and replaced with new filter. Now it won't bleed out the air or something isn't allowing fuel to get to the injector lines. Did the bleed process and have fuel at he bleed plug in the injector pump. No start. Removed fuel injector lines and no fuel coming out of pump, Is there a screen or another plug that I can removed to clear out the pump or has the pump gone bad? picture is a saved copy of a 1700 for reference only

when I take the fuel lines from the pump to the injectors off then turn the engine over will the fuel come out of the pump and spray all over or just trickle out?

It will be more of a trickle at the pump. The injectors are spring loaded and only open when a preset pressure is reached. The spray will occur from the injector tips when the pressure is reached and the injector opens. With the lines unhooked removing the injectors from the flow there is little pressure developed.

Use caution around injection systems. The high pressure spray or a leak can inject fuel under the skin which is serious, even fatal.

Only my front lower crankshaft pulley there are no line to mark TDC or firing. It is still painted blue and the marker pointer is there but nothing on the flywheel. And help?

Why are you suddenly worried about timing marks? Timing doesn't have much effect on fuel supply or delivery.

I have the must change out my fuel injection pump. Getting everything aligned before removal of old pump so I can get the new pump installed properly.
