Hi Guys
I was on my home today after drinving on and off for about 120 miles today.
On my way back on the motorway cruising at 80 mph I felt a few slght
imperfections in the running of the engine.
I thought for the first one or two times that it could be the road but then
I knew it was the cruiser acting up.
I slowed to 70mph and then 65 mph just to see if there was a difference in
the running.
There was a difference, all the cars that i had passed for miles back now
were passing me and I could swear that the people in the cars were smiling
or was that just me being paranoid.
Well I still felt the imperfections every so often but not too many of them.
It was like a little miss fire or jerk , but only for a split second and
then it was gone.
I got to within 1 mile of my house and at a roundabout the cruiser just
died.
Not that nice a thing to find you have a steering like a bumper bar and
brakes to match.
I got a tow home from a passing neighbour and now I would like to know a
few things.
I thought the engine might be seized but I checked the oil level and it
seems ok.
I tried to start it and it wont hold revs at idle at all.
I tried to start it and rev it but it just dies after a split second at rev.
I started it and it will rev from the engine bay but will not keep idle
rev.
I only tried this for a few seconds and let it die.
So I think if the engine was seized it would not start and run at all.
I pumped the hand pump and it started but then died.
I tried to keep it running from the trottle in the cabin but it dies.
When revved and it dies I can hear the what appears to be the turbo spining
for a second and then it stops but I think this is normal.
I have power to everything electrical.
I took out the air filter and its fine.
Any ideas would be welcome before I let Toyota have it on monday or tuesday.
I did fill up with Diesel this morning and yes I checked it was Diesel with
the receipt just in case I filled it with petrol, but it was Diesel.

In my total-know-nothing-but-have-a-gut-feeling mode it sounds like fuel
starvation John. Maybe the pump is able to supply enough fuel to fire up but
not enough to continue running.
Blocked fuel filter?
Knackered fuel pump?
Too much vacuum in fuel tank?
Just random thoughts I'm afraid John.

John,
I first thought your TPS was giving trouble but this usually lets
you limp home in safe mode. Now I think you have fuel stavation. I
suffered from this once but it was more serious, mine would not even
try to start. you have a fuel filter in the tank, easy to get to and
check, just takes a while, this may be blocked with particles of rust,
(they all rust eventually). There is also a fuel filter built in to
the pump. Mine had blocked with metal particles from the pump
mechanism, the pump was wearing itself away due to lack of
lubrication. This is apparently a problem with cheap diesel
(supermarket). If this is your problem put a diesel additive in the
tank about every 3,000 miles, one that is designed to lubricate the
pump. To establish that you have a flow of fuel crack an injector
union loose, you should get diesel out when you turn the engine over.
There is not a good way, that I know of, to check the pump as it is a
2 stage one. The first stage sucks fuel from the tank, the second is
higher pressure for the injection system. It may be possible to use a
plastic bottle to supply the injector line and squeeze it gently, wait
for a response from some one that has messed about with the system.
Regards, Clive.

John,
Going one further from Peter, take off the fuel tank filler cap
and see if you can start it.

Hey Peter
Thanks, I am at the stage of random thoughts and a lot of other thoughts
like why me again, when i take such good care of it. Just goes to show you
there are the lucky people who dont care about what they drive and drive all
the time without problem and then there are people like me who care and look
after the vehiicle and get a lot of hassle. Dont figure at all.

Hey Clive
Thanks, I have already replaced the in tank fuel filter a short while ago
and cleaned the inside of the tank aswell.
I also use Millers fuel additive during every fill up, but dont know why as
I cant prove it works, but just hope it does.
I do get my diesel from Tesco but know that the supplier is the same as the
main garages because I saw the fuel tanker delivering one day.
So I reakon its the same fuel as a lot of the garages in the country.
But I will check every thing tomorrow if it stops raining that is.
I reakon I should just walk every where and lose weight

Hi John
I do (more-or-less) look after my 'cruiser but I also have a point of view
that you can fiddle with things too much.
I'll happily grease propshafts, bearings, etc, change oil and filters but
some things like dismantling fuel tanks I feel can do more harm than good.
What I mean is that once you start dislodging rust and junk that has been
happily sitting there for years then more seems to appear thus blocking
things up just when you thought it was clear.
Just a random 2-penneth.

Hey Peter
I know what you mean, but when I say I cleaned the tank it was through the
inspection hatch located under the rear seats while I was replacing the fuel
filter there.
It was done about 9 months ago and it was amazing what was in the tank , I
found long strands of something like tread that would be used for stitching
clothes.
I have a spare fuel filter for the engine compartment but cant remember if
you turn it clock wise or anti clock wise.
God just to know its not the engine seizing is a big plus believe me.
If it was I think I would just burn the rest of it out at this stage.
cheers

John,
Here's a proposed routine:
checking for vacuum in the tank
checking / changing the fuel filter,
checking for air getting into the fuel lines
blowing compressed air into the fuel line back into the tank
running the engine on clean fuel supplied directly into the injection pump

Hey Frederick
It maybe a 92 but it has had more new parts than maybe its value on the market, including an engine rebuild and fuel pump rebuild.
I think it cruises at the 80mph very nicely usually that is and dont think it is trashing it one bit.
I think a low geared JCB is for moving slowly over rough terrain as should the cruiser in the same situation.
But it is a top of its class road vehicle aswell and will only be in the mid 2000 revs while doing 80mph.
Also a good run is supposed to purge the engine of all the impurities that acumilate from slow driving most of the time.
Its very well looked after and if the constant driving on a motor way at 80 mph for about 25 miles is too much for the king of 4x4s to handle.

Why me ? Because these vehicles are not designed for thrashing along at 80mph on motorways. Eventually something will break at that pace, especially if you have a few miles up.. it's a 92 for xxxx sake. Look after it, and it will look after you.. These cruisers are designed for crawling over rough terrain. Big tyres, lots of linkages in the drive-train, all-wheel drive, low revving diesel... how do you figure that a constant 80mph is looking after it ?

Hey Roman
Thanks, now you know id ask.
But is the only way for checking the vacume in the tank to listen to the
hiss when you undo the fuel cap.
Checking air getting into the fuel line, how, it was ok this morning,
It wont be moving to any garage to blow air into the tank, Its grounded for
being bold today literally.

I have found that if I can keep the speed down to about 50, I can achieve 29mpg, but at 70 and over it's down to 18mpg, a comfortable cruising speed for my 80 seems to be around 65mph.

Landcruisers, like any car, have their own 'natural' cruising speed... and for me it's not above 70mph. It may be revving in the mid-2000s which might look ok compared to a 4 cyl hatchback, but that's not really the way to assess suitable cruising speed. The other indicator of a cruising speed that will ensure long vehicle life is mpg... on the TLC, mpg falls away rapidly after 70mph, which means the engine is working hard to overcome air drag. Certainly, if you plan to keep the vehicle indefinitely (or forever), then high speed is a killer in the long term. There are many stories of 1 million mile cars, and their owners will always tell you that moderate speed (and frequent oil changes) were the secret of success. What's more, if you ease up, then you get to spend more time behind the wheel enjoying your cruiser. Cheers. Fred.

John,
If you have a tank vacuum then you will be able to run the engine
with the cap off the tank. While you try this take out the fuel
filter. That is Romans numbers 1 + 2 sorted.
Blowing through the fuel lines is not a good way of checking
them for faults, it is a good way of clearing them of muck.
Pressirising a fuel line tries to expand any neoprene pipes and this
is not replicating the pump action. Sucking through them can cause any
weak pipes to collapse, this is what the pump in the cruiser does.
Regards, Clive.

Hi Guys
Just a little update on my situation.
I spent most of the day messing with the cruiser after taking all your
advice and a special thanks to Julian who has been very helpful on the end
of the phone.
I started with trying to see what the cruiser would do and then seeing if
it changed by various tests.
It would start but took more effort than usual and would keep running if I
kept the revs up by pressing on the foot trottle, but once I eased off on
the pedal it would die.
The turbo green light is coming on as usual at about 2200 revs.
When I kept sustained even pressure on the foot trottle the revs would
increase and subside bye about 400 revs.
I tried starting it with the fuel cap off, no difference.
I tried priming it then starting it, no difference.
I tried priming it then starting it then priming it again and starting it,
no difference.
I drained the filter from the bottom, it primed and drained againand primed
again,
no visable real dirt or water only a very fine stuff like dust but floating.
I tried to start it with fuel cap on and with it off and it did start both
ways but would not idle, no
difference
I changed the fuel filter nad filled the new one with Diesel prior to
fitting and then primed, no
difference.
I used the hand trottle to keep a rev of about 1000 but it still flucated, I
then primed it a few times and there was a slight difference in the running
of the engine.
I then checked all hoses in the engine bay and they seem to be fine.
I checked the coolent colour and level and its fine.
I then took the rear seats out and checked the filter in the tank and its
fine and no visable dirt that would cause a blockage.
I disconnected the fuel feed to the pump in the engine bay and then blew
through this feeder pipe with my mouth and captured all that came out of the
pipe in a clear cup at the pumpend not in my mouth.
Very slight discolouration of the diesel.
I then blew again with the engine end of the pipe covered and I could not
blow at all.
I then blew with the same pipe half covered and it was possible.
I then put it all back together and tried to start it and yes you guessed
it,
no difference.
I checked the idle screw and it does not appear to have moved , no visable
clear marks on the treads,and is tight.
I contemplated on adjusting this but then thought it wmight seem to cure the
issue but would only cover up the real problem
So im none the wiser sad to say after all that.
Cheers

John,
You need to eliminate the faulty section of the fuel line between the
tank and injectors. Try running the engine by feeding the injection
pump from a can of diesel (make sure it's clean). Remove the fuel hose
between the filter and the pump. Get a longer section of a suitable
fuel hose, connect one end to the injection pump, dip the other one
into a jerrycan. If it runs OK, find the fault between the pump and
the fuel tank. If it doesn't, seek help from a diesel specialist.

Hi Roman
Thanks, Ok will do tomorrow.
Why do you think its possibly a fault in the pipe from the tank as I have
tested this.
