Good morning,
I bought my first Land Rover yesterday and now I'm trying to start it.
I bled the fuel system based on the workshop manuel. I think there is no more air left in the system . But I'm still not able to get fuel to the injectors.
The injector lines are loose and no fuel comes out when cranking the engine.
I also checked the fuel solenoid.

Do you guys have any idea?

Not too sure with that IP but with all working correctly, you should be able to get some fuel from the injector lines with the flare nuts loosened at the injectors whilst pumping the lift pump.

Thanks for your reply,
Already tried that, no fuel gets to the injectors.
 
no fuel will flow from ip until its cranked, if you slacken feed from filter at the pump and work loft pump is there a good pulsed flow,is solenoid working,what made you bleed system
 
I plugged a vacuum pump at one of the injector hard lines. A lot of air and a little bit of fuel is coming out. What are the common air leaks I should check?

Once you are able to bleed the air out of the IP body bleed screw by pumping the lift pump, then, using a fully charged battery, loosen the flare nuts at the injectors, crank the engine, tighten the flare nuts as fuel appears.
If there is no fuel appearing then as has already been said, check fuel lines, filters, lift pump, air leaks on feed side of IP, fuel solenoid (does this pump have a solenoid ?), if there's a stop lever instead of a solenoid check that is in the run position, that could be a possibility.

I replaced the fuel filter a few minutes ago. Now I try to bleed the system again. But it seems that the hand pump only works at half the way.
Yes the pump has a solenoid, I checked that already. It's working.
 
I wanted to bleed the pump by sucking the air out. why won't this help?
you cant do that, you bleed it at the pump body as gazbo posted,fuel will only flow out when engines cranked, if theres no air in the pump,solenoid is working,pump is been turned,has the engine run since youve had it?

you may need to turn engine part of a turn if cam is pressing on the internal pump lever,lift pumps are very prone too failure but you dont notice till system needs bleeding

OK that makes sense to me.
No I bought a not running car.

undo feed pipe and work lift pump actually see if its got a good flow of fuel,after its got clean fuel to pump bleed screw,remove the cover on front timing case in front of injection pump, 3 screws see pump turning or not

When you have got the lift pump off the cam, try bleeding the filter again from the top banjo. You will need to pump quite a lot of fuel through the filter, put a bucket under it. When you are sure there are no air bubbles coming out, move on to the pump bleed screws.

Did you use a quality filter, and are you sure the 4 rings(all different) are in the right places?
 
I think air is not the problem, we bleed the whole system many times. There is no air left and there is also no fuel leak. It has to be a failure in the IP. The pump doesn't build any pressure and not even a single drop of fuel is coming out. Do you guys have any idea where I can get a used or refurbished one?

A Delphi agent, or any reputable fuel injection specialist, should be able to rebuild the pump, if you can find one in Germany.

If not, you could try ringing this chap, he might rebuild one and send it to you.

Sounds like you have been through the bleed process as comprehensively as possible, might now be time to establish if the IP is in fact rotating, the pump drives off a "skew gear" from the camshaft I think, (I'm not all that familiar with this engine), but @jamesmartin will have seen a lot, and may know if there could be possibility of failure in this area, it could be a failure somewhere in the drive gears or drive tangs on the pump, check that the pump is fully seated in its mounting. Without being there to have a look I can only suggest that if there is a place somewhere on the IP you can witness the pump shaft actually rotating, if its not then there is no way it will push fuel. Which could be the reason the vehicle was sold as a "non runner".
