Hey Lio
Thanks fior that piece of unpleasant information.
To tell you the truth I did the blow bye test but not too sure what i am
looking for really. I could feel something but not sure if the pressure is
correct or not that I am feeling.
Now I am worried cause it does fit the issue, not running at idle but will
on revs.
And also all the oil consumption over time Ahhhhhhhhhhhhhh
But what the hell could cause this if it was the case.
I have a guy who knows more about this than me coming today I hope and so
may know more soon.
But if it is that case of the rings /pistons etc, ill sit down and think
where to go with it
cause it would be a bit too much to get it done with buying the bits and
getting someone to do it.
I think I may get the push bike out of retirment.

Hi Guys
Just a little update.
I had help to look at it last night Thanks Brian.
But could not figure out the problem.
It died one last time last night and would not start again no matter what
was done.
So now its time for the RAC guy, see what he says and if he can fix it
great, if he cant maybe they will transport it to the Diesel specialists on
the flat bed.
Im going to by pass Toyota as they will only send it out anyway to others
and charge me for the pleasure.
The thing is the pump was only reconditioned about four years ago, but maybe
it will end up being something really silly that i will be able to laugh
about later.
Whats the chance of that happening with my record.
John 92HDJ 80 1HDT still grounded

 

[Guest]

A silly question that must have been asked before but I can't find it.....
The pump does actually pump the fuel doesn't it? I mean disconnect the fuel
feed from the injector rail and crank the engine to see if diesel comes
out??

[Guest]

Hey Peter
This is my view of things at this stage.
The fuel is sucked from the tank through the fuel filter housing by the
injection pump, out the other end and sucked into the injector pump, then
ist pushed through the injectors into the engine.
We had fuel all the way into the injector pump but when he (cracked) as he
called it the injectors one by one, we had a little dribble but then
nothing, instead of a good spray of diesel.
The sad thing about this whole situation bar it actually happened is the
fact that I have learned a lot and done more than I would have done
previously.
Before I would have called the RAC straight away and be done with it not
caring nor wanting to understand .
Now I want to understand.
Poor Brian last night with me asking im sure 1000 questions.
cheers

[Guest]

John,
Are you confident the fuel shut off solenoid is opening. This is
contained in the injector pump.
If it is not then nothing will be getting into the pump.
Sorry but was unable ring the other night.
Gareth.

 

[Guest]

John
Sounds to me like you are not getting fuel into the cylinders.
The fuel, by the time it reaches the injectors is at pretty high pressure
and I would have though that if you unscrew the injectors then you should
get a good high pressure spray from them. It doesn't sound like you are
getting this, but you are getting a good flow of fuel to the rail (from the
pump)?
If this is the case then you either have a blockage in the fuel line between
the pump and the rail, or the injectors are not opening, either because they
are not serviceable or because the engine management system is not telling
them to open.
So it "could" be an electronics / ECU problem? Or maybe even a broken wire
between the ECU and the injectors??
Can you borrow an ECU and swap it to check?
RAC man should be able to test for this as well I would think.
Pete

 

[Guest]

Ahh, wait a mo.
By "cracking the injectors" do you mean that you took the injector out of
the head and looked to see if fuel was coming out? Or did you undo the union
between the fuel rail and the injector?
If the latter, and you are getting no fuel flow then it's not being
delivered by the pump - end of story.
If the former and you are sure that you are getting fuel from the pump then
it must be the injectors / ECU that's at fault.
... surely...???
Pete

 

[Guest]

Peter,
It is a purely mechanical system. If diesel is entering the pump past
the shut off solenoid and yet none is coming out then there is a problem
with the pump or possibly the pump drive. Cracking, or slightly undoing
the nut on each of the injectors is as you say a good way to quickly
determine if the pump is delivering fuel to each cyl.
John,
When you remove the fuel filter from the housing is it always full of
fuel? It should be full to the brim.
Have you tried connecting the Walbro pump and supplying pressurized
fuel to the injector pump?
Gareth.

 

[Guest]

Hey Gareth
I dont know at all.
He could not get it off/open, but it did have power to it all the time and
not just when the key was in.
I dont know if that is suppossed to be that way or something happened in
the process of looking at it.
This solenoid is on the oposite side of the pump that the feeder pipe is on
so how does it controll the flow of fuel.
cheers
john

 

[Guest]

Hey Peter
I dont know where or what the ECU is even to look for it.
The RAC man came I told him what I checked and he said OK ill get it sent to
the Diesel place, and all without taking out a spanner.
O he did try to turn it over once but that was all, I suppose to be sure it
would not start. So it gone to the doctor or the mortician.
cheers
john 92HDJ 80 1HDT

 

[Guest]

Hey peter
On the injector there is a big nut which connects to the head, these were
opened, then there is a smaller nut on the top I think of the injector this
was also open, but no fuel. Sorry but I was in the cruiser cranking it by
the key so didn,y see it in action really.
cheers

[Guest]

John,
It's begining to sound very much like the problem I had, the
filter in the pump being blocked. Only the fuel cut off solenoid could
produce a similar problem.
Regards, Clive.

 

[Guest]

Hey Clive
I think if the filter in the pump is blocked then its with bits of the pump
which means the pump is knackered. If its the solenode I presume you just
replace this with a new one which would be cheaper that getting the pump
fixed.
cheers
john 92HDJ 80 1HDT

 

[Guest]

John,
"power to it all the time"
Well if someone had asked me I would have said that it should only have
power to it when the ignition was on. Surely with 12v to it then the
solenoid is "open" i.e. allowing passage of fuel. In this situation you
would be unable to switch the engine off, that has certainly been my
experience of diesels.
I'm just mulling this over, does the solenoid prevent fuel entering the
pressure side of the pump or does it stop pressurized fuel from exiting
the pump. Its function is to stop the engine as fast as possible and it
achievs this by interrupting the flow of diesel. So if it was on the
pump inlet then theoretically fuel present in the pump could continue to
run the engine. If it is on the outlet then the engine stops ASAP.
Fellow listers ---- Have I got this correct?
I think I would be investigating the solenoid further, removal and
test.
ECU'S - we don't have such things John - thank goodness.
The 24v - HDFT engine has a TPS - Throttle Position Sensor, I have no
idea if the 12 v -HDT motor has one, however I cannot see this affecting
matters.
Be aware that there is a small filter in the injector pump. I think
this is found where the fuel inlet pipe is connected to the injector
pump. Remove the banjo bolts and the copper washers. Look down into the
pump and you should see a cylindrical filter. Remove carefully - you do
not want to drop it as it will disappear into the bowels of the engine
compartment. See what is blocking it.
Good luck.
Gareth.
Gareth.

 

[Guest]

Hey Gareth
That makes sense to me but then that does not say much.
Now I know what the solenoid is for.
It was tested with one of those guages and read 12.3 when the key was in and
when i took it out.
Would it be possible its shut closed.
I know I dont have the cruiser here now but am finding this very
interesting.
We did open a nut that had a small spring in it and what looked like a ball
baring in there, which was full with fuel.
No worries about the phone I know people have lives and work.
No ECU great another thing that cant go wrong, only leaves 99,999.
cheers

[Guest]

John, it may be faulty, permanantly in the shut position. It would not
be the first or last one to do it.
Gareth.
