Most of your problem is your not getting fuel to the pump so either you have a fuel blockage or a filter blockage or pump diaphragm has air getting into it
a pin hole will cause the problem.

Why doesn't tractor start after injector pump rebuild?


I'd be suspicious that the injector timing is not correct.
When the injector pump was rebuilt, it had to have been removed from the engine.
There will be timing marks on the gears and they have to be lined up for the fuel to be injected at the correct time.

94 Dodge diesel finally got it running and it stalls and doesn't want to start we pump it up and stil it still doesn't want to start


from your description there is still air getting into the pump
check that the fuel filter is on correctly and air tight
check and bleed all the fuel system including at the pump
loosen the injector lines at the injectors and crank until there are drips of fuel at the nuts
re-tension the nuts as you keep cranking as this process bleeds the air out of the injector lines
CAUTION--KEEP FINGERS WELL CLEAR OF THE NUTS AS THIS FUEL IS AT 20.000 + PRESSURE AND WILL PENETRATE THE SKIN

How to change injector pump on CAT 428f backhoe?


Try to loosen the nuts on the fuel lines going to the injectors and crank the engine till all the air bubbles are removed from the system. Don't crank the engine for longer than 30 sec at a time letting the starter cool down before cranking again.

Bobcat 773 wont restart after dying out where do i start?


if the bobcat starts and then runs for a short time then dies the first place to look is the fuel system.fuel filters are the most common problems that i see replace those first.i have also found some junk inside the pickup tube inside the tank.there is probably a ball type hand pump to prime the fuel system.give that a squeeze and see if its hard.if thats the case there shoud be a small screw on top of the fuel filter.loosen that screw and see if fuel comes out when you sqeeze the ball.if your changing fuel filters this is also where you blead air from the system,keep pumping untill there is only fuel and no air.if you still get air after pumping for a long time then your sucking air into the system between the tank and pump.after you get fuel there close the screw,loosen the injector lines going to the injectors,crank the engine,and tighten when fuel comes out (keep clear because that is high pressure fuel).after you get fuel at all injectors and they are all tightened it should start.

Just changed the fuel filter on my navara D40 dual cab started it, ran for 5 seconds and won't start again. Have pumped the top on the filter for ages. HELP


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.

2004 5L Hiace fails to start however whines.


this is the first thing i would do since it has not run for a long time.
1 make sure it has fuel, check filter, loosen the bolt securing the fuel line to the pump and see if fuel is coming out, if it does you have fuel in the injection pump. retighten.
2 loosen nuts on injection lines to injectors 4 if you have 4 cyl. eng.
and crank the engine (start) until you see fuel coming out from each line then re-tighten lightly. start the engine*, it may take a while for the engine to run if the glow plugs are not working properly. once the engine is running its time to bleed or purge air out of the line, to do this
loosen one at a time the nut you have re-tightened lightly until fuel and air come out, tighten when no visible air bubble only solid fuel stream. do this on the rest of the injectors, you will feel the engine run smooth.

*if there is no fuel coming out after continuous cranking the engine for 30 sec to a minute, injection pump may have a problem possibly the rotor vanes inside the pump is stuck due water in fuel and engine not running for a long time. you may have to have the injection pump overhauled and recalibrated.

My golf 1.9 tdi is miss-firing


Check the fuel lines, fuel filter, what is the mileage? If it is high than it might a sign of injector pump or injectors.

SANDERSON TELEPORTER, HOW DO I BLEED THE LUCAS FUEL PUMP ON A PERKINS ENGINE


Perkins is a hard engine to prime. Fill the fuel filter with clean diesel, there should be a hand pump on the left side(looking at the front of the vehicle) . There should be a bleed screw on top of the filter housing. Loosen the bleed srew and pump the hand pump untill you get a steady stream of fuel from it. Tighten the bleed screw. Loosen the injector bonnet nuts approximately 1 1/2 turns on all of the injectors. Turn the engine over until you see a steady stream of fuel from the the injector bonnets. Tighten the bonnet nuts, pump the handpump approx 10 times and start the engine. Give it half throttle until it stops stumbling and all of the air is worked out of the system.

My john deere 990 wont start. it's not getting diesel to the engine


Check there is adequate fuel to supply engine. Check there is no damage to fuel lines and that the fuel filter is not plugged. Yours is a Yanmar diesel engine withe an autobleed feature which is supposed to bleed the air out of the system automatically. It may incorporate an electric fuel pump also, but some don't. You can prime the fuel system to the injection pump with the manual lift pump if it is equipped with it. After establishing fuel to the injection pump, loosen the nuts that hold the fuel lines onto the injectors approximately1 1/2 turns. Turn the engine over until you see fuel coming from the injector nuts. Tighten the nuts to 24 inch/lbs of torque, start the engine and run at 1/3 throttle untill it runs smooth.

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.
