No diesel getting to fuel filter- engine running then stalling when push accelerator

[Petekoad]

I have a problem. All has been fine until a couple of weeks ago when the engine would struggle to get beyond 3500 revs. So I thought first thing to do was change the fuel filter.

Problem now is that the filters not getting any fuel. I primed it by filling it with diesel. It ran and then started to judder and when I pressed the accelerator it died.

It now starts but dies as soon as you press the accel. Take off the filter and it is only a 3rd full. Refill and same again.

The lift pump does not appear to be doing anything. Read that you need the engine in the right place but not sure how to do that. Help !!!!!

turn the engine a few degrees to get the pump off cam,then pump by hand but only works very last part of stroke.\simple and cheap to replace.

 

[defcrazy]

dont waste time trying to prime it ,that hand pump needs replacing .

Slacken the return union on the fuel pump start then close it when running good

Is this a trick question :whoosh:

Thanks for all your suggestions. Picking up lift pump in a couple of hours and will let you know how it goes.

Cleaned out the sedimenter and all lines are clear so I am hoping the pump is the problem.

Sorry to ask a dumb question but how do you manually turn the engine?

Just for completeness it is a 95 plate Discovery 1 manual 300tdi.

Thanks again for your feedback.

Unplug the solenoid wire on the injection pump (stops any possibility of the engine firing up), then give the ignition key a little quick 'flick'.

 

[Petekoad]

So . I have fitted the new pump and it is still not drawing any fuel into the filter when I pump.


Could I have fitted it wrong? Arrgh!

Any suggestions?

BTW . There is a difference to now in that it seems to rev much higher a first before losin power and then stalling.

Open the return union on the injection pump and start it it sounds like air to me

 

[blue beasty]

check the fuel line from the tank to the pump. If its split it wont leak fuel out but draw air in as is negative pressure

 

[lazydog]

On top of filter housing is a bleed screw loosen 1/2 turn a start engine tighten when air has come out.

Sorry to be dumb but will this get the air out or will it show me something?

Done this and nothing comes out. No noticeable pressure and certainly no fuel...
