MF240 diesel quits running after 1 minute

John After changing fuel (1 filter type) and air filters Perkins runs for about 1 minute at 700 rpm then quits. Will restart after about 15 seconds.

I have bled system many times including
2 bleeds on pump - 3 at injectors - 1 on thermo start. I am bleeding top connection on injectors not larger fitting on sides. All conections appear tight.

Also can I cap both ends of thermostart and disconnect wire?


Mac The fitting on top of the injector is the leak off pipe and it is not a bleeding point,to bleed the system,first bleed the filter/s,then the pump,bleed the bottom screw first and the top one last till bubble free fuel comes through,open the injector pipes a few turns at the side of the injector,on full throttle spin the engine over and when fuel spurts from the pipes tighten them up and start,unless the ball valve in the thermo-glow plug is leaking fuel into the manifold you should leave it connected,but you can block it off if need be.

Joe Had similar problem. The new fuel filter was letting air into system. Try a new filter and make sure it seals correctly. Good day!
