bobcat 773 getting little fuel to injectors

[bbuchsen]

1 and 4 injectors are getting very little fuel to them. Bobcat is running on two cylinders. If I bleed 2 or 3 the engine quits running. I'm hoping that lines maybe plugged instead of injector pump going bad. If I unhook the lines and use the hand primer, will I be able to flush the lines. Not sure what else to do. The lines are getting some fuel to them but it is very little. Injectors 2 and 3 are getting plenty of fuel.

the injectors hem selves are not plugged up are they? if they sit for some time, the nozzles can stick inside the injectors....

No, I have taken the injectors out and cleaned them. They are fine. I've also switched them around and they are working fine

Sadly, the only other thing is the injector pump....... If you have good fuel pressure to the injector pump, it's the only thing left.
You will need a shop to do the work, the innards are adjusted so the elements inside deliver the exact same amount of fuel.
