Hi John
I am sure Julian will tell you in more detail but to my knowledge the cold start system is outside the pump. The idea is that there is a wax filled cylinder that pushes against a lever that is part of the linkage to the throttle cable and when cold it moves and makes the pump squirt in more fuel till the heat stops it from doing this. I guess?? My diesel man explained it to me so I may have got it completely wrong. also I don't like all this talk of special pullers etc. My guy had no issues with pulling off the pump he had all the tools there, big hammer, big spanner, even bigger hammer, chisel etc. But seriously all he does is pull off pumps and fix them. The only thing that stopped him was my lack of money! Is there anyone else near you that can look at it??
I just had a look in my book and I could find nothing like you described inside the pump. Julian has a very good firm near him. Maybe pull the pump and send it to them to be rebuilt?
Good luck
Simon

Hi Guys
Just another update for all of you who have a clue what I am going to try
and explain.
I think for the mechanically minded you may know what the hell im talking
about, but for people like me its just too much gobblti gup.
Now please bear with me while I try to explain after his technical overload
of information.
The problem with the cruiser that led to the breakdown was indeed the
injector pump going ga ga.
The delay in getting to this point of actually knowing what was wrong was
that he needed a puller tool to get the pump off of the engine, something to
do with gears or cogs I think.
Anyway he neede this tool and he had to have it make specially for the
cruiser.
So I guess that he does no work on cruisers like the VX and every
aplication is different from truck to truck to car or digger etc.
He says the problem was a part inside the injector pump which
regulates the flow of fuel in very cold conditions by advancing the timing a
bit to help compensate for the cold.
I asked him a few questions just cause I do and this is what he said.
Its a small part that acts like a valve which is spring loaded and this
actually broke off and went around the injector pump and lodged.
He recomends or is going to bypass this part altogether as I dont need it at
all .
I asked about the cold starting and I heard a little chuckle and he said
that we dont need this at all and it would only be of use in the Artic
climate or places like norway etc.
He did say if I wanted he could order a new assemble for the pump which
could be expensive and would have to come from Japan.
He reasurred me several times with the same words ( you dont need this part
unless you are going to live/travel to very cold climates).
So to find out that I have a part in the pump which I dont need that broke
because of age and nothing else will cost me dearly.
He explained that when they make the vx (top of the range) back then Toyota
were fiddling with all sorts of devices to make the cruisers more able to
deal with all sorts of climates.
And its only after this pump spec that electronic pumps were and are the
bees knees.
So who says education is cheap
Maybe if I have it wrong someone on the list can set me straight, would not
be the forst time.
cheers
