check if there is bleed screw on the pump and if so bleed there while pumping the filter pump. Next loosen off the injector line nuts and crank over until you see fuel droplets at the nuts . keep cranking as you tighten up the nuts and it should go. Diesels not starting after filter changes ( or running out of fuel) is a result of air in the system / pump/ injectors.
IS THE ENGINE TURNING OVER? IF IT IS YOU MAY HAVE TO BLEED AIR FROM THE FUEL SYSTEM, IF THERE IS A MANUAL PRIMING PUMP, USALY BUILT AS PART OF THE FILTER HOUSING OR REMOTELY MOUNTED ON THE FUEL SYSTEM PUMP THE PLUNGER THILL IT GETS HARD THERE SHOULD BE A BLEED SCREW MOUNTED OPEN IT AND STROKE PLUNGER UNTIL YOU SEE BUBBLE FREE FUEL COMING THROUGH CLOSE OFF THE BLEED SCREW AND PUMP PLUNGER TILL HARD AGAIN THEN TRY STARTING
I got this from Haynes Diesel Engine Repair Manual. I bought it for my 6.2.
1. Remove the fuel filler cap and air cleaner assembly.
2. On filters without an air bleed screw, place a rag under the filter to soak up fuel and detach the lower clip FIRST to release pressure and then the top clip. They pop off with a screwdriver.
3. On filters with an air bleed screw (top passenger side) drain fuel from the filter by opening the screw first and the engine water drain valve (engine front near thermostat) if it has one. Detach the clips and remove filter.
4.Make sure the seating surface is clean and place new filter in position. On non-air bleed filters put the upper clip on FIRST. On air bleed filters secure both clips, then close the valve and attach a piece of hose to the bleed port into a pail.
5. Air must be purged BEFORE start up, so disconnect the pink wire from the top of the injector pump and crank the engine in 10 second cycles with a 30 second wait time until clear bubble-free fuel comes out the lower fitting or air bleed. Connect the lower clip on the non-air bleed , close the bleed hose and reconnect the pink wire.
6. Start the engine and let it idle for several minutes to purge any remaining air and check for leaks.
Hope this helps.
you cannot change filter without bleeding it you can however fill the fuel filter with injector cleaner that can be put into filter and NOT into the fuel tank this will help also u can get a external primer pump and attach to the OUT side of filter and pump the fuel through good luck
If this is a diesel you should not use starter fluid unless the glow plugs and glow plug controller is removed. If this is a diesel you most likely have air in the fuel system.When changing fuel filter on a diesel fill the filter container with clean diesel,screw the top of the fuel filter canister on open the bleed screw and turn the engine over until only clear fuel (no air bubbles)is bled from fuel system. Then you may have to turn loose the connector on the innjectors to bleed more air out of the fuel system.
The fuel filter may have a bleed screw, undo the bleed screw slightly and crank the engine over until fuel spurts out ,if it does then retighten screw. If that doesn't work then the next Best way is to crack open the nuts on the injectors and get someone to crank the engine over , as fuel starts to come out of the joint retighten them up.
This should get most of the air out, any remaining will quickly clear after the engine runs for a while.
sorry. i changed the fuel filter on my kubota rg30 and cant find the bleed screw to bleed it.
