Oil & Fuel foton 404 tractor fuel problems

[johnpa]

I have just recently purchased a FOTON 404 FROM A DEALER --- i have replaced filters and any rubber lines with new ones... I have bled this tractor and all lines to thefuel pump and to the injectors and still am having problems getting it to run. I will get it started and it will run for 5 minutes or so and then shut down. i have also used the pump on the fuel pump to keep it going. When I got it it would run real well on flat ground but as soon as i went up a little grade it would cut out. Like i said it has been completely bled out and still am having problems. I NEED TO KNOW IF THERE IS A FUEL FILTER IN THE FUEL PUMP. VERY FRUSTRATING

FOTON 404-2005--SL3105BT NEED TO KNOW ANY SUGGESTIONS WOULD E HELPFUL THANKYOU JOHNPA---HARMONY PA

I would bet that you have water in the fuel, Diesel bugs,Dirty fuel filter.There is also a screen in the fuel tank, in sediment bowl, and inside the bolt that holds the fuel line from the tank to the bottom of the primer pump

TOMMY THANKS FOR THE REPLY I TALKED TO HAROLD ALITTLE EARLIER AND I DID CHECK THE FILTER IN THE BOTTOM OF THE PRIMER PUMP AND IT WAS COMPLETELY CLEAN. THE FUEL IS CLEAN AND THE MAIN FILTERS HAS BEEN CHANGED,THE FUEL WAS EMPTIED AND NEW FUEL PUT IN,SEDIMENT BOWL IS CLEAN. THE ONLY THING IM QUESTIONING NOW IS THAT IS IT POSSIBLE THAT WHEN I OPEN UP THE PUMP TO PRIME IT IT LEAKS A LITTLE FUEL WHEN I PRIME IT. IS THAT A CONCERN OR NOT. ALSO ON THE FUEL PUMP I FOUND THAT WHERE THE AIR BREATHER IS ON THE BACK END OF THE FUELPUMP WAS DRY OF OIL IN IT SO I PUT SOME OIL IN IT ABOUT 6 OZ. I DONT KNOW IF THAT WOULD BE A CONCERN OR NOT THANKS FOR THE INFO... I STILL THINK SOMEWHERE IT IS SUCKING AIR AND I CANT FIND IT. THANKS JOHN FOLTON SL3105BT

I have also seen the Black rubber line from the Sediment bowl to the injector pump collapse internally and slow down the fuel flow, you are starving for fuel somewhere or sucking air

Isolate your problem first. When the engine dies for lack of fuel, spin off the fuel filter housing. If it's not full, something in the fuel path between the tank and the filter is impeding fuel flow. That's the low pressure side. If it's full, the problem is AFTER the filter. Meaning - if you've got good fuel flow INTO the injection pump - it's a problem on the high pressure side.

GREGG THANKS FOR REPLYING.----i think it might be the hand fuel pump I open the bleeding bolt ahead of the primer pump and im still getting air out of it but i think it is the primer pump leaking air into the injection pump. I have all good lines no leaks else where replaced a small rubber hose from the fuel tank to the sediment bowl to make sure it wasnt collapsing. replaced fuel filter =tightened all lines up there are no leaks there. also drained fuel tank and replaced with new fuel in it -checked injection pump filter it was clean === fluid moves thru everything just fine but some where there is air getting into the pump so im going to replace the primer pump it only leaks when i open it to prime the lines and stops when i push down and tighten the primer back in place== and the fuel filter i checked it after it quits and it is full of fuel===== THANKS FOR YOUR INPUT JOHN PA

The priming pump is also the lift pump, and they use the same spring loaded check valves, and is driven off a cam by a push rod in the fuel injection pump. As far as leakage goes, some can be normal, just so it doesn't leak when it's screwed down. Diesel bugs can attack, corrode, and pit the check valve seats rendering them almost useless. Check your fuel pressure, you should be getting about 10 psig at idle, and about 25 psig at governed speed.
Did you remove the sediment bown from the fuel tank and check for an internal screen? You may have to thoroughly clean the fuel tank.

THANKS BOB IM currently looking into replacing the fuel pump. I believe that is where the problem is currently- thanks for all other info----john pa

When it dies is there fuel in the fuel bowl? If not its the in tank screen.

THANKS FOR REPLYING CHRIS--YES I DO HAVE FUEL IN THE FUEL BOWL AND FILTER AFTER IT SHUTS DOWN IHAVE CHECKED IT A COUPLE TIMES TO BE SURE----THAHKYOU JOHNPA

The primer pump - or lift pump - or hand pump - whatever you want to call it, is on the low pressure side of the fuel path. It's only coincidentally attached to the injection pump (IP). It doesn't push fuel into the injection pump, it pushes it to the fuel filter. Loosen the flexible fuel line between the fuel filter housing and the IP. Loosen it at the IP end. Then unscrew the hand primer and use it to push fuel. If fuel comes out the loosened fitting, the hand pump is still good. If there is no flow, the next step is to isolate the cause on the low pressure side. It's likely either the hand primer or one of the fuel screens.

If there is fuel, tighten that fitting back up. Then locate the individual high pressure fuel lines (steel) that connect the IP with the individual fuel injectors. There's a hex collar that fastens each line to its respective injector. Loosen each hex collar, then crank the starter. What you want to see is fuel spewing out each of the lines. If no fuel, it's an IP problem. If fuel is flowing, it's an injector problem.

THANKYOU GREGG FOR RESPONDING ILL LOOK INTO IT IM CURRENTLY WAITING FOR A PRIMER PUMP THAT I HAVE ORDERED AND SHOULD BE HERE IN A FEW DAYS--THANKYOU JOHNPA

 

[Bob Rooks]

When you go to replace the lift pump, remove the large hex plug first (it's spring loaded), that will make the job go much easier. And by the way, did you know your "caps" key is stuck? Using all caps is considered shouting or bad taste.

ill use lower case letters i didnt know that fact-- my situation for reasoningof larger caps is that i am partially blind andit makes it easier for me to see the larger letters thankyou john pa and thanks for the info

Thanks for letting us know, it helps. Did you know that Microsoft has built in features in the Windows OS to assist challenged users? There are medium and highly contrasted settings just for such cases, as an example. There are also more tips here: http://www.microsoft.com/enable/
