So I have BF6L913 that I just recently swapped into one of our drill rigs. My question is about the starting aid on these motors. How do they work? Let me explain what I think I see. So off the back of the injection pump is a little magnetic solenoid. That has one wire going to it. I hooked it up to a push button. So when pushed, it makes a click. There is a steel line that goes up to the manifold on top of the motor. There is nothing else. I have taken this line loose, started the motor and held the push button, and nothing comes out of the line. I have never seen anything come from the line that come from the rear of the injection pump, and goes to the manifold. There is no glowplug anywhere also. And I missing parts to make this setup work? And why isnt it pumping fuel? Or is it even suppose to?

That thing is kinda neat. Wonder if Cummins ever used those. Some of their intake elbows have a removable plug. That would probably use less current from the battery than glow plugs or a grid heater.

it might also not to be so restrictive as the grid heater ends up becoming when the engine is heavily tuned...
