SOURCE: John Deere will not start.

If you have gas running down to the carberator ( take the fuel line off and make sure there is gas running to it or there may be a screen or filter plugged by the tank or on the way to the carb) if there is gas there the problem lies in the carb itself. If you have some mechanical ability you should be all right as it is not rocket science. If you are comfortable with taking the carb apart the first thing i would check is the needle vavle. With the carb apart you will see a big brass looking thing this is the float, right above that is the neddle valve, that is the first place they seem to stick on me. Move the float up and down if the neddle above it doesn't move or sticks there is your problem. Spray it with carb cleaner and see if it moves freely. You may have to dismantle the carb to get it to work freely. If it won't buy a carb kit and install all the new gaskets needle valves and jets ( this is a very good ideal any how) Also make sure any little ports in the carb are open ( in the bottom of the carb there may be tiny little holes that are plugged) find a very small wire to clean them with and also make sure when you are done you can spray carb cleaner thru them. This is why they have a small straw on the can with it ( watch your eyes and wear safety glasses as you never know where it will spray out from) That stuff will dry your skin out fast so don't get it in your eyes and you may want to wear rubber gloves. Also be very careful when putting back together as there are little pieces that like to slide around and fall out or may get bent even worse you don't want them in your motor. Also try to count every screw you turn as these are jets and you will want to put them back to the place they were set at cause it's a pain to get them set right by adjusting them later. Do not force anything putting it back as you may bend the jets or float and you will have to take it apart again and replace them as well. Take your time and be patient and you will be just fine

Testimonial: "thanks...you gave me encouragement to give it a try. I took off the shroud, air cleaner box and couldn't take off the carb as there are no heads on the four bolts that hold it on. Looks like it was designed not to be removed? I took off an inspection plate on top of the carb and cleaned all of the channels and ports within with carb cleaner and compressed air...still no gas flowing thru carb...unless I force with compressed air. Any other thoughts? It is a twin cylinder OHV B/S. Thank you. "

SOURCE: John Deere 5420 has no fuel from tank to filter

John Deere and it's lack of engineers, located the fuel tank below the engine/filter assembly, so it won't gravity feed. The little pump in the top of the fuel filter is worthless. The easy fix is to install an inline diesel fuel pump with a overpressure line off a blank fitting from the fuel filter, which will allow excess pressured fuel to flow back to the tank. What I did was install a fitting with a fuel hose about 2 feet long that has a lawn mower fuel cut off, with a section of hose after it, that can be plugged, when not used. Anytime fuel prime is lost to the filter, then it's a major effort to get it back. This is the cheap way. If you disconnect your fuel line the fuel flows all the way back to the tank, however I believe there is a check valve located underneath the tractor, before the tank, which keeps it from going all the way back. Anyway, I use a large cc syringe to pull fuel up to the filter. After each pull, I close the lawn mower shut off to keep the progress. Empty the syringe and then open the valve and pull some more. Once you have plenty of fuel to the filter, then I close the red fuel shutoff on the back of the fuel filter (closes the line to the tank). Then I push some fuel with the syringe toward the injector pump, while cranking the engine. At this point you don't want it to start, because you will pull all the fuel from the filter, because the red shut off is closed on the back of the filter. After only one or two "pushes" , then close off the lawn mower shut off, open the red shut off on the back of the filter, and crank. Mine usually starts about 5-15 seconds from starting to crank. DON'T CRANK TOO LONG, THE BOOK WARNS ABOUT OVERHEATING THE STARTER. What stupid engineers designed this? Hope this helps. As a side note the fuel hose off the tank is one size, and then it goes through the check valve and changes to a smaller diameter, to go to the filter.

How do I change the fuel filter on my 3020 John Deere diesel tractor


Leaving the fuel valve on the tank in the on position will allow fuel to run through the line & keep the air purged during removal. On the other side between the pump & the filter, having the new filter topped off & speedily installed will lessen the chance of air entering the line. Once the filter is installed, open the bleed screw at the top of the filter. Just my redneck way.

HOW DO I BLEED THE INJECTORS ON A JOHN DEERE BACKHOE.I BELIEVE IT'S A MODEL 310


I have the 410 model,ran it out of fuel plenty of times in the past but never had to bleed the lines due to the electronic injector pump. If it just stalled then you probably dont have an air pocket problem. Most mechanics dont recomend using starting fluid on these engines,but if you are careful and dont try to keep the engine running on it you will be fine.If it starts and quits try changing the filter,or cleaning the tank filter.

1987 John Deere 510 Backhoe


have you tried cracking the injector lines for air?
if you crack the lines 1 at a time fuel should spay out if nothing comes out after a few moments the injector pump could be bad.
and you did fill the filter before you put it on right.

Diesel backhoe ran out of fuel and won't start now?


When my dad's JD450 would run out of fuel, we would have to bleed the whole system. Loosen the bleeder nut on the top of the fuel filter assembly until the air is out, then tighten. Gravity should do this. Loosen the injector nuts, then tighten each in sequence as they stop bubbling, starting with the one nearest the fuel filters. Since the engine has to be cranked while you're doing this, newer ones with the automatic glow plugs will probably start about the second or third injector, and you can finish tightening from there, Older systems you have to manually engage the glow plugs, and that probably won't start until the last injector, if then.Most injector systems will handle a little air, just make sure the bubles are small and not too many.
