Hello I need some help on my no starting little guy. My brother bought this Shibaura P155f a few months ago and it has ran great till the other day. I used it for the better part of the day with no problems. The next day it had a hard time starting but finally started but lacking on power. When I would try throttle it up it was slow to rev up but was running smooth. I then drove it about 20 feet and it died and now will not run. It was low on fuel so I topped of the tank but no help. So I thought that maybe it was lower on fuel than I thought and that it had got air in the system. I tried bleeding the injectors but never really could get much fuel out but a lot of bubbles. I back tracked the fuel system and discovers that there was no filter on the system. The filter sediment bowl was missing the filter. The engine will start for a few seconds then die while I'm trying to bleed the injectors. The rear injector just pushes out tons of bubbles and never any straight fuel. The engine will not start but only when the injector line is cracked on the third injector and no other injectors. This thing has me baffled and am not sure whats up. When the tractor was purchased it came with a manual that is not to the same tractor but very close. It also came with a web print off of the injection system so I'm guessing it has had a simalar issue. I follow the process the manual stated for bleeding the system but get the same results that I had did first before looking at the manual. The third injector is the only one I really get any activity out of while bleeding and the other two just spit out small amounts of fuel. So is my injection pump bad or is there a trick? Any help would be great. Thanks

Welcome to the board, always good to have new blood around here.
You mention sediment bowl, being I'm not familliar with your tractor I'm assuming you mean a conventional sediment bowl under the fuek tank. I've never saw a gravity fed sediment bowl under the fuel tank with any more than a flat fine screen just above the level of the glasss. Unless there was another filter element also in the bowl that screen alone won't keep enough dirt etc. out of the system to protect any diesel injector pump and injectors working very long. I don't want to be a dooms dayer, but I'm afraid that if contaminats have gotten far enough in the fuel systen to clog the injectors that you are going to need some help from a diesel repair shop.
Somehow you need to get a filter in the system or you are going to have the same problen again.

re: No start P155F Shibaura
You don't bleed a diesel by bleeding the injectors. There should be bleed screws on the the sediment bowl & one on the injector pump. Bleed them of air one at a time starting at the one closest to the fuel tank & work your way to the injector pump. The injector pump will compress the air & only get a little out at a time.

re: No start P155F Shibaura
Have you checked to see if free fuel flow coming from the tank? It could be something as simple as a piece of floating trashed pulled into the outlet when fuel was low. Do get filter in there.
