    Am thinking it probably has a Simms inline pump? You need to take the side cover off and see if the rack is stuck.A drop of oil and a poke back and forth with a screw driver should free it.

    It'll be a rotary pump I think so dont think they can get a stuck rack or anything like that. Are you getting fuel to both bleed screws on the pump? Some dont have bleed screws and some have just the one. Thoses with no bleed screws normally have a pipe back to injector returns so they as self priming of injector pump but still have to bleed injectors.

    There is a filter on the inlet of the rotary pumps too under the feed pipe fitting. If thats clean and still no fuel to injectors then pump off and recon job.

    If old type inline pump then it could be a stuck rack which can be unsiezed by removing the side cover and working the rack back and forth with screw driver and bit of oil. If inline pump then you may need to put some engine oil in the pump anyway unless its a later version that is fed from engine.

    Its a cav pump.

    Re: FORD 3000 FUEL PROBLEM

    When you say it bleeds OK do you mean to both the bleed points on the DPA or just to the filters ?

    Have you tried slackening off the DPA end of the injector pipes ?
    There are more engines killed through lack of water than through lack of oil

    Only one bleed screw on it no fuel at injector port.

    you will have to bleed injectors on the old things, so crack off all injector pipes and crank engine over till fuel comes out then tighten them up and it should start.

    They can be hard to get going doing what ace says open injectors and crank it over what I do with ours is slightly pressurise the fuel tank works a treat

    Re: FORD 3000 FUEL PROBLEM

    Usually only need to slacken one injector pipe. I have always had success slacking the injector pipe at the pump end, not at the top of the engine.
    Main thing is to ensure diesel gets to the pump and bleeds until free of air at the pump, tighten, crank while slacking the injector pipe. Beware of high pressure fuel as it can damage your health if it penetrates your skin.

    All air is out of system pump turns ok nothing coming from unions.

    Sorry if this seems an awkward question but If nothing is coming from the unions how do you know that all the air is out? Surely you'll only know that with pump turning and pumping out a constant flow of ribena!

    Re: FORD 3000 FUEL PROBLEM

    A quick way to bleed the little Fords is to open the bleed screws, give the filler a a good wipe and blow into the tank to create some pressure. I must admit not doing it that way for many years but it worked. I use an RIB/dinghy low volume pump with a rolled up plastic bag (as a seal) these days.

    Re: FORD 3000 FUEL PROBLEM

    If you're getting a good flow of fuel from the bleedscrew when cranking it,and definitely nothing at any injector pipe,I would guess the metering valve is stuck in the stop position. You could try tapping the pump while moving both the throttle and stop levers back and forward. If it's no different then it's either pump off time or if you feel confident enough,you could lift the lid off the pump to see if the mv lever is free. You would most likely need a new gasket though as they can be hard to get to stop leaking after opening.Usually only recommended that a specialist goes in there!

    Re: FORD 3000 FUEL PROBLEM

    ive had the lid of many cav pumps, just lift it very slowly and make sure you get things disconnected and know where they go, also do not over tighten the top down to much or it will crack easy, as already said you will need a new gasket or make your own as there sods to leak after being taken off,

    You will see a rod inside a long fine spring which is hooked onto a lever at one end.That lever is part of the metering valve.Chances are it's stuck in the closed position.You don't need to remove the throttle or stop spindles from the lid as in the picture unless replacing the o rings. Just disconnect the governor spring and lift the complete lid off.Remember which hole to reattach the spring.It's important!

    Just a quick update removed the cover all looks free fitted new o rings and top gasket, pleanty of fuel bled still no go took bango off pump there was fuel injecting but not enough pressure to go through bango .

    Try taking an injector pipe off at the pump and blowing back through the union with compressed air while cranking the engine, this may be enough to free up the pumping plungers in the pump if they are stuck.

    Re: FORD 3000 FUEL PROBLEM

    After trying Islander's suggesting,it wold be worth checking the regulating valve. The internal filter below the fuel feed pipe on the end of the pump sits over and around it.It's not hard to remove it and see if it is sliding freely in its housing.It is vital that the bits are reassembled in the correct order or the engine still won't go.Sometimes it is easier to remove the end cap (4 small scews) and reassemble the valve pieces on its side. Can't find a good diagram to post!

    Although if the filter is blocked,it wouldn't bleed...........

    Many years ago I took one of them filters out with delivery valve to clean it. Put delivery valve back in upside down and it wouldnt go!

    It was a mf 390

    Fitted a known to be good end cap this morning still no go ,when i bleed it there dont seem to be much of a flow but when i press the starter there is a good stream coming out.Do you think i need pressure on the incoming fuel as there is no lift pump at the moment i have feed fron a can about 18 inches above the pump

    Have you looked for a second bleed screw on the back side of the pump have seen one before with the bleed screws on the back side for some reason.

    If you have plenty fuel out the bleed screws then you got no choice but take pump off for overhaul. They are quite cheap to get overhauled anyway

    for the price you said they quoted get it done its not worth the time playing around if its u/s its u/s simple cos even if you got it to pump fuel it might not be correct pressure and might not even run, sounds a enough job to get fixed correctly and then you know its done & move on,
