injector pump woes

[Guest]

John,
When the CS mechanism packed up, I went straight to AAI and had it
delivered in a few days, so I can't advise about with alternatives.
What I can say, though is that I would check first if this particular
part of the injection pump needs to be a genuine Denso part or a Bosh
part will do. Theoretically, any diesel specialist should be able to
tell, but sadly they were not created equal.

Hi roam
So you obviously thought that it was important to get this CS mechanism, so
would you leave it out and be happy and if not why.

John,
I don't put too much faith in global warming, that's why I preferred
to have the pump properly repaired rather than having the job botched.
I suppose Craig Vincent will know if it essential or not.

Hey Roman
When this happened last year I did ask Craig or he told me anyway that it
was not really impostant to have the CS.
Is there any other function for this other than better Cold starting.
I know I could just let this guy go about what he does but I can't miss the
opertunity to get more knowledge.

John,
I would not say it has any other function other than better cold
starting. All it does is increasing the revs and advancing the
ignition until the engine is sufficiently warm. Some engines never had
it.

Hi Guys
Just had the verdict back from the second shop to look at the injector pump.
He took it off and bench tested it but could not get it exactly to specs
what ever they are.
Fitted it back on and changed the pipes around the way he said they should
be.
No improvement at all still, vibrating and will not keep the revs.
He says because he got it after the rebuild he does not know what went into
it.
There could even be parts that are not correct.
So the bottom line is he does not know what is wrong unless he takes the
pump back off and takes it apart and starts to replace bits but he said to
do this could work out very expensive.
He said to look for another second hand pump and rebuild that one.
The number on the pump is missing and he is not sure he has the right
number.
Still up s----- creek without a cruiser on the road.

John,
On my pump the number is Denso 096000-6420
My advice - send this pump to AAI and ask them if they can part
exchange it for another, guaranteed s/h pump.

Hi John,
Saw this post and thought of you,
http://forum.ih8mud.com/showthread.php?t=157185.
I doubt that will work or do anything, just might be worth a try if it's
your injectors instead of the pump(I am no mechanic)? I would assume they
have been cleaned previously anyway.
Also just another thought my mate had an lj70 that produced a lot of white
smoke and would stall and hardly rev, it turned out to be the fuel pipe on
the tank had corroded and had a hole in it and was finding it hard to suck
the fuel from the tank and mostly air was getting through.
Replacing that solved his issue?
Just another thought that probably won't be your problem .
Martin.

Hi John,
What part number does he want to know? I can give you part numbers from
the EPC.
If he has tested the pump and it is still giving problems I would
suggest two things:
1. Mention to him the possiblity of air getting into the fuel line - is
this something he has checked?
2. How has he set the timing? Has he done it statically or dynamically?
3. Tieing in with 1 above, has he tested the pumps ability to suck up
fuel - not one of the standard tests for those pumps, but worth doing.
I would check these out before spending more money on a second pump.

Hey Roman
Thanks for the number.
I gave it to the guys and they said they will follow it up.
He did say while on the phone that they think the housing is off something
different than the landcruiser and why change the housing.
Anyone got a pic of the injector pump that should be obn a 19992 cruiser
handy.
thanks

Hey Julian
I asked him these questions and he said it sucks fine , no problems driving
etc , says its not the injectors cause this would manifest in other
problems,
says no air is getting in anywhere,
says the timing is bang on,
but thinks the housing is not correct.
If housing is not correct doesen't want to strip it down cause they dont
know what they may find and its all money per hour and per part.
Is it possible to have a different injector pump housing that would still
fit the cruiser

Hi,
I don't know much about the 80 series, just another thing to include in the
equation of possibilities, aren't these fuel pumps controlled by an ECU in
the 80's?

Hi Lubo
I have already done this today thanks.
I have to weight up how to get this fixed the best way i can after being to
two injector pump guys and money is flowing in the wrong direction.

John,
I have just remembered it is possible to re-build these pumps
with parts from the wrong manufacturer. One is Denso and the other is
Bosch (I think), if the wrong parts have been used you can have
problems.

Hey Clive
So it is possible to rebuild it if your a plonker with the wrong bits and it
will still run.
Could a different housing be used in the same way.
It just seems suspect that the number is missing or possible scratched into
it as this guy says.
Is the number on a plate or just a sticker.

John,
I am not sure of the housing. I had mine re-built a while back
and was warned about a mis-match of parts, I think it was Roman that
mentioned it.

Hi Guys
Is the injector pump the same on the manual and the Auto 12v engine.
I got the cruiser back today and while its no worse its no better either.
Still vibrating and not keeping the proper revs.
It does have some more power than it did so maybe that's to do with the
crossed pipes which he discovered.
Something like the fuel return from the injectors was going back to the
turbo instead of to the pump.
The vaccum was going somewhere else and not to where it should.
Thanks Roman the IP number checked out so he was working on the right
numbered pump.
He said he did take it apart and every thing seemed fine but he still thinks
the housing is not belonged to the cruiser.
The rear of the Ip is the cruisers because of the six injector outlets but
he says the front can be from any Toyota and he is just suspecious of this
part.
I dont know if this would make any difference but then again I dont know
much anyway so trying to piece all the info together as usual.
He said my choices are to get another pump from a breakers, one that has
more than likely not been toutched at all and he could test it out and it
may be fine, then straight on it goes.
Or to see if I can live with the issues with the IP as it stands.
He can overhaul a pump for about 450 euro which includes vains /springs and
other bits.
But he said he will not over haul my pump because it could be a waste of his
time and my money because once he starts to replace more than the usual
basic bits it gets very expensive indeed and he doesn't know if the correct
parts are in there in the first place.
I dont know seems strange when he had a look but cant tell if the parts are
genuine Denso or not, but obviously it does make a big difference because
the IP is not running right.
So it would seem a waste of time to send the pump off somewhere else if im
not sure the housing is correct or the expensive bits on the inside are
correct either.
Trying to live with it could be difficult and also trying to get an IP that
could just go on would be even harder.
More than likely it will be another pump that will need to be over hauled,
ouch.
