Help... Bleeding a 110 system

Previous posted on here regarding a C Reg 110 2.5 NA Defender
(converted from petrol to diesel). My boyfriend has started to look at
it but we currently can not get hold of a haynes manual (not even sure
if this will be of any help at all anyway)

Can anyone tell us how you go about bleeding the fuel system. We tried
to turn it over and there seems to be fuel up to the injector pump but
it does not go any further towards the injectors. It has been standing
for around a year unused (last started 8 months ago).

Also, does anyone have any details on the injector pump as we were
going to attempt taking it apart and checking it wasnt stuck etc.

Any help would be very much appreciated.

DONT take it apart.

If you don't know how to bleed it then you stand no chance of putting an
injection pump back together.

If fuel is getting to the pump, and not the injectors them check the
fuel stop solenoid is getting power.

Bleeding with the ignition switch on will clear the pump body of air
once the filter etc. is bled. Then crack off and injector pipe and crank
using starter.

The 2.5NA is a pain to bleed compared with TDI's but should be straight
forward.

Thank you for the reply, boyfriend is currently working with classic
cars but doesnt really have much knowledge of diesel, so is learning
what he can. He tested the fuel solenoid that seems to be working
fine. We still cant seem to get any fuel out the injector pump. Any
clues?

OK...

make sure the battery's charged.

person under bonnet: wear eye protection.

check that there's current to the stop solenoid, also that when you apply
current to it you hear it click. If there's no current or no obvious
action, remedy the solenoid first.

Working at each injector, loosen the pipe union about half-to-one turn -
ideally, you want to hold the injector body still but not always essential.

have an assistant crank the engine, with ignition on. Observe the fuel
pipes (where you loosened them) and you should see froth and then diesel
squirting out. for each pipe, once there's no more froth, just high
pressure diesel, nip up the pipe union. Once each injector has been bled,
and no more air emerges, that cylinder should start firing - if you do 1 and
3 in that order it should, once you've got 1 and 3 firing, run by itself
without cranking while you do 2 and 4.

If you get no fuel at the injector end of the delivery pipes, then the sop
solenoid is not working, or possibly the thing that it pushed inside the
pump is stuck. Unscrewing the solenoid from the pump should allow you to
test it and see that it operates.

I'm assuming you've primed the pump at this point - there's generally a lift
pump with a lever or other priming device - identify the feed and return
from the diesel pump and having slackened them make sure you get diesel from
both, then tighten 'em up again.

Have a look at this site, lots of free downloadable manuals there...

Don't worry, they are in English.

Another thought

Have you ever seen the engine run?

When i rebuilt by 2.5 diesel, it took me about 3 or 4 batteries worth
of cranking before i got fuel through into the right places and
managed to start it.

I've always bled it by working through the fuel system loosining off
connectors and then cranking till fuel came out.

you should be able to hand-pump the low-pressure parts, and only need actual
cranking for the injector pump up to the injectors.

If your lift pump works . I did hand prime up to the injector pump.
It is the plumbing after this that takes ages to fill up.

Hi all

thank you for the replies, we managed to get the engine running. The
injection pump needed a little whack to free whatever was stuck and
voila! My boyfriends dad is manufacturing a lil union to join the
loose pipe from the rocker box cover to the air pipe to recirculate any
oil so it is burnt off. (someone has cut off half of the air manifold
which is where the loose pipe was connected to we assume) Any other
ideas appreciated?

It is good to see it running again after it has been standing unused
for just under a year...
