2012 DEERE 310K backhoe. Crank strong, no start. I removed

Customer Question
2012 JOHN DEERE 310K backhoe. Crank...
2012 JOHN DEERE 310K backhoe.
Crank strong, no start. I removed both fuel filters and both were empty. I checked the fuses and relays because the fuel pump wasn't working. Fuses and relays are good and fuel pump works but is very weak and slow to fill the filters. I'm getting a full 12 volts to the pump. I replaced the fuel pump and filter assembly and also the secondary fuel filter. I bled all the air from the system 5 times and it will start sometimes and other times noting at all. When it does start it only runs for less then 5 seconds. I'll reprime the fuel system and bleed the air then it will start for 5 seconds or less and stall again and again. I removed the return line from the injection pump that goes back to the fuel tanks and blew it out with compressed air and that didn't fix it either. I'm at my wits ends here and on starting to think its the injection pump itself. Please help. I maintain this backhoe with new oil and all filters every 150 hours or 3 months whichever comes first. It has less the 1100 hours on the clock.

Hi I'm Wayne

I will help you with this

you did correct on all trouble shooting, (good Job)

sounds to me you are sucking air, or a blockage in the fuel pick up

What I would like you to do, is a 5 gal container a line/hose from the container to fuel filter

see if it runs that way , then we can work further, let me know

Good idea. I should of thought of that. Can I get back to you tomorrow? I'm not home to do that right now. If it runs from a fuel container, should I pull the pickup from the tank? I never had a pickup removed from a backhoe is it similar to a truck pickup?
Mechanic: Wayne, Journeyman replied 1 year ago

When I use the 5 gallon tank to suck fuel out of instead of the tractors fuel tank it still doesn't start or run. Anything else you can think of?
Mechanic: Wayne, Journeyman replied 1 year ago

Morning

OK next do you hear the fuel pump running

it is mounted on top of the fuel filter

also check the relay , follow the wire from the fuel pump
