thug the uber reliable 4trak is dead.:-(
I went on a journey to Wales some 9 hrs form me in north east Scotland, got there ok, no problems, stayed overnight, did the visit, did a bit of hill climbing, no problem, done it all before, next morning, dead, wont fire up, tried bypassing the fuel filter, dead, tried the AA still dead, well it turns over, fuel is reaching the injectors, but it will not run, we got it started but got no power or revs above 2000 out of the loud pedal, and that was using a can of plus gas, got wrecked home, that took 11 hours, boy , was my arse numb, thought the timing belt may have jumped a tooth, checked that, nah spot on , so I am left with two thoughts, loss of compression or pump failure, did think it was a air lock in the tank but that’s been blown through, scratching head now. Any one got any ideas?? I don’t have the kit to do a derv compression test, but the engine turned over by hand when I was setting up the timing a might to easy.
I have had thug some 3 years and it has served me well, I brought it off a farm with a buggered gearbox and no mot from £250.00 and a duff one of evilbay for £125.00, ripped out the old engine and box out them both and swapped the gear and transfer box straight over, changing the bell housing and shaft, did a bit of welding, scrapped the second vch, my mate had the inside for his and stuck the rest back on evil bay. in total thug owed my £27.00, three mots later (at trade) I have spend £30.00 on a clutch cable (parto co robbin bastards) and £6.00 on a rad cap, oh and £50 on six new tyres and four wheels, had the igni key snap in the barrel usual shit, loose gearbox nuts (we have all been there), towed my 605 on its trailer some 600 miles plus
So all I can say that it’s been thoroughly abused, ragged up and down the UK for £223.00 plus fuel for three years of fun so I will be sorry to see it go. It’s been a blast. But if I can’t fix it, it will have to go the next vch will have to have cruise control 
how many times have I said that
Power to the Fourtrak
Could be many things, the obvious is the fuel pump from your description of the symptoms, or an internal crack in the cylinder head.
Other suggestions could be a damaged or broken camshaft, and/or a valve problem, including movement of the camshaft sprocket on the cam.
Another thought is the fuel shut off valve is working incorrectly, not opening correctly, or it is stuttering and constantly opening and closing, limiting fuel supply to the engine.
Partial engine seizure is also a possibility, due to low oil pressure or flow.
Begin by eliminating the obvious, compression test the engine, this will eliminate wear, valves, camshaft, etc; and time the engine to ensure none of the pulleys have come off the woodruff keys and turned.
Check all diesel pipes to ensure they are not sucking in air anywhere.
Entrust the expertise of a local diesel engine injection specialist to eliminate the fuel system itself, they can test the pump operation, injectors, and other problematic areas.
Finally; based upon the information gathered, it will mean a stripdown of the engine to try to ascertain the problem/s, it may be that it is cheaper to buy an engine, or accident damaged vehicle with a good engine to replace yours with.
dead trak
thanks assassin
i have done a sniff test on the coolent side and have got the front end in bits checking the pullys and timing all of which are spot on no leaks in the fuel pipes etc its just that when i turned the motor over by hand,there didnt seem much effort required. anyway next step is to reset eveything and try and start it again, if this fails its a toss up between stripping the pump down, removing the head, putting another lump in it or tossing in the towel, considering how much i have spend on a 18 yr old motor i think it may have well gone to the scrapyard in the sky, but i think i have had my monies worth out of it. we shall see
Injectors.
Any possibility the injectors are partly blocked?
Something simple maybe, have
Something simple maybe, have you checked all the fuses? Its possible there is a solenoid in the fuel line not getting power, which is why it will run on spray, but not fuel- alternative source of fuel.
There is an "engine" fuse in the fuse box, check that one.

dead thug
cheers guys
i have checked the fuses there all okay and i know fuel is getting to the injectors, but Mace has put a thought in my head, i will rip them out in the am and blow my air line through them. i could have gone with the fuel starvation bit if this had happen before the trip but afterwoods, don't know. i am going to try some different oil and and a bit of drev from a different source in case i got some watered down shit, but i still feel in my bones that it is terminal but then i always look for the darkest cloud first, and knowing my luck it will be something stupid that i've overlooked
todays update
okay then, thug fires using easy-start as fuel, the timing is spot on , all fueses intact, and every thing where it should be, however when cranking there is no derv being pushed through the pump, i know its getting there i have cracked all the pipe ends to make sure, it just that there is no fuel being pumped through, well there is no fuel being spurted out at no1 injector under cranking
has anyone ever taken any of these apart neither my daihatsu cd nor my autodata disk go into any great detail as to the problem areas, so no idiots guide, i aint ready to send it to the knackers yard yet
cont
for my next trick i shall be removing the injector feed pipes and cranking the engine to see if i get fuel from the pump, if not i am leaning towards a dead or stuck fuel cutout solenoid
Fuel pump warning.
Take extreme care that you avoid pressuring any fuel onto your skin.Pump pressure massively exceeds the pressure needed to inject a mist of diesel into your blood stream! Very dangerous!
Might be best taking the pump to an expert repairer - your health is worth more than a few pounds and the expert will know what to sort.
Fuel pump warning.
thanks for that Mace i wasnt thinking of sticking my hand down there to find out
i was thinking of using some cardboard to get a spray impression on, it will either work or it wont 
update
okay then.
i have found the fuel stop solenoid, but you can’t remove it without stripping the pump (not something i wanted to do on a tuesday afternoon) }:) so i guess that’s means pump out time, but before i attempt that i think i am going to visit milner off road and try a new filter, my reasoning behind this is 
after much swearing and gnashing of teeth, i have zero, nothing, not a triple of fuel coming from the pump under cranking,
1 i had to hand pump fuel to the injector pump
2 i know i bypassed the filter to attempt to start the vch in wales but i reconnected it before the aa arrived so if there was too much crud floating around inside i may have dislodged more and blocked the filter
3 to make sure that it isn’t a problem
The pump will have to wait until after Christmas, I know I could dump it in the garage and have it done for me, but I really want to find out how this thing works, so it’s off to do more research and bug the local diesel experts some more, and spent more money.
Did you just look at the
Did you just look at the fuses, looking for a blown one, or did you test or replace them. Those spade fuses can look OK, but be dud. Been caught more than once with that.

It could be the stop
It could be the stop solenoid on the pump. First check there's power to it. I have had stop solenoids fail on CAV pumps and guess it may occasionally happen on Bosch / Denso. They usually unscrew from the delivery head of the pump body (above the injector pipes) and the ones I've worked with have a spring loaded stop plunger within. The spring and plunger can be temporarily removed and the solenoid body replaced. This will allow the engine to start, with the caveat that its won't stop by the usual ignition key means.
I've not had a fourtrak pump in bits so could be off the mark with some of this. I think there's a plastic cover on newer models, presumably this is to prevent intrusion / bypass of the vehicle immobiliser.
fuel cut off
thanks JW i have come to the same conclusion, the fuel cut off valve has power going to it but zero fuel coming out of the pump the only problem is i cant get the bugger out without stripping the top of the pump off, which is something it is become too cold to do at present, i mean i guess the pump is as old as the trak 18 years so its had a good life, but I aint ready to kill it off yet, luckily my Shogun is still running at the moment so it can wait
Shut off
Do not be deceived into thinking it cannot be the fuel shut off valve as it has power going to it, inside is an electromagnet with a valve end attached, this is usually what causes the problem. Many people assume that just because it has power going to it, it must be working; to test, put your hand on the valve and get someone to turn on the ignition, you should feel it click if it is opening, if not it is the internal electromagnet which is defective.
Additional problems could be that the internals of the pump are defective, the injection pump may not be producing any internal pressure, this could be something as simple as an internal seal, or something else broken or snapped.
Shut off
i haven't, but i have managed to obtain a pump at a silly price, and i do mean silly, does it work, well it been taken off a working vch, so i guess we will wait and see, it will either work or it wont, if it doesnt i have two to take apart, if it does i have one to gut, if the vch fires up problem solved, if it doesn't it must be something else and its back to the drawing board, we shall see.
