Mechanic's Assistant: What is the complete model and serial number of your machine?

Br275 snocat 46096957

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Fixing myself in the middle of nowhere. changed fuel filters(they had just been changed prior to sending to site. Engine stopped working 1 hour into the day. pushed air into fuel tank and was able to get fuel up to transfer pump, but when cranking fuel doesn't get to injectors. checked to make sure that transfer pump shaft was turning and it was it has an actuator and when key is on it does actuate and wired it open just to make sure that it was actuated and still no fuel to the injectors

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

Is there an electric fuel pump that draws fuel from the tank and to the main pump?

Hi my name is***** will be glad to try to help. If you have fuel to the injection pump and bled of air there should be an electric fuel shutoff solenoid on the main injection pump that shuts the fuel off in the injection pump at key off. test all fuses and test for power to the solenoid at key on and off then verify proper operation. If a manual shutoff by linkage or cable there will be a lever on the pump. Let me know the engine make and model from the engine tag. We can follow up as needed

Thanks for the info. If the transfer pump is pushing the fuel ans supplying good fuel to the injection pump with no restrictions or leaks sucking air, etc. and the fuel shutoff is working and opening up the injection pump up for fuel on but weak or no fuel delivery after cracking loose the injection lines and good fuel transfer pump supply pressure it points to a weak/failed injection pump. When a pump is weak sometimes running out of fuel is all it takes to finish it off but just be sure the shutoff is working and you have good fuel supply before condemning the injection pump. Let me know
