OK, so I thought I had run out of fuel. My CK30 fuel guage was showing 3/4 of a tank when she stopped. But I was looking at the bottom of the tank when I opened her up. I decided to change the fuel filter at the same time(99 hours just seemed like a good time). I changed the filter, re-filled the fuel bowl, and have been cranking and cranking for over a week with no sign of firing.
So far I have found:
1. No fuel in the injector lines from the fuel rail to the injectors.
2. When opening the lines at the rail, no fuel comes out of the rail.
3. The fuel shut off solenoid is working, but with the solenoid removed, the little plug inside the rail does not move into the open position on its own.
4. The fuel pump on the side of the motor does not pump much fuel, barely a trickle comes out while cranking.
5. I used a vaccuum pump to fill the fuel lines all the way to the banjo bolt on the side of the fuel rail. I have a steady flow of fuel using the vaccuum pump, but when I turn the tractor over, barely a trickle comes out.
My questions are:
1. What moves the fuel shut off inside the rail? Is it fuel pressure? or is there a broken spring in there somewhere?
2. If fuel pressure moves the rail, then the problem must be the diaphragm pump on the side of the motor. Is this common?
My CK30 was bought in 08/05, mostly used for mowing, she has 99 hours.
Is there anywhere to find on-line diagrams of these assemblies? I hate to pay for a haul-in when its just something stuck that I can fixmyself.
I also wanted to say thanks for all the information and troubleshooting ideas I have read on here over the last few days.
