has to be fool or air...... collapsed turbo hose?
check all air path including filter.

Right
towed him back from L'pool (and burst me rad on the way back)
new lift pump
piped fuel direct from lift pump to fuel pump
Got fuel at injectors but not a lot
all rockers working as they should
took plunger out of stop valve
Engine starts and fires evenly on all four for about 2 seconds then goes lumpy then stops
Engine wont respond to throttle lever on pump.
It will sometimes idle for a minute but very lumpy.
Dark grey / black smoke chuffing from exhaust when firing.
never fails to start instantly but lumpy idle only
Engine sucking fiercely at intake as it should.
So it's getting air and a little fuel but what can be stopping the fuel getting through from the pump to injectors?
Does the diaphram go wrong on top of pump?
Motor only done just over 100k
Baffled

Had the inspection cover off and nothing loose
Tom said that it happened slowley over about ten miles or so, loosing power by degrees until it would only tick over, cant see any water in fuel or blockages anywhere. The pump shouldn't go wrong but fuel not getting to injectors in correct quantity I think
Update
Removed the fuel cap......no different
Blew fuel back into tank with air line...no different
Removed diaphram etc from top of fuel pump cleaned and replaced...no different
Started engine and whilst it ticked over rough, managed to spray some carb cleaner into the intake....she ran better, coughed and then ticked over on all four cylinders
She will now tick over nicely and rev quite a bit on the throttle but seems to be starved of fuel still so going to put a new fuel filter on tomorrow just in case it IS blocked after all.
Fingers crossed

Good thought but 90 and not got one, gonna feed the lift pump from a container of derv tomorrow and see if that makes it run.
It'll eliminate tank problems anyway.
Might have to try a brand new lift pump in case the pressure aint right, we put an old but good one from a td on it.

corroded fuel pick up pipe under seat or loose fuel bango bolt will start and rev to about 1K RPM then die out. Me thinks a tiny air leak getting into fuel system possibly Jai
Fed the lift pump direct from a jerry can tonight and the problem still the same.
Notices fuel bubbles coming from bleed screw on top of filter but no change when sorted it out.
Going to change the cambelt on Sat as it is due and fit a new lift pump but do one job at a time to see which cures it (if any
)running out of ideas
Still not going..
Eliminated fuel quality problem
Lift pump.....renewed
Fuel Filter.....renewed
Injector pump...swapped and re timed
Injectors..tested ok
Cam belt...renewed and re timed
Inter cooler pipes ok
Induction sucking like a gud un
Exhaust pipes clear
Turbo working
Rocker gear moving valves up and down ok
Plenty of Compression....still to get a gauge on it though
Still to consider.
May have been sold a duff pump but doubt it
Compressions may be down but why suddenly would it do that?
Injectors may still be iffy even though they have been tested.. still to change them
It's not drawing air in anywhere and there is plenty of fuel pressure at the injectors
The cam and pump timing are ok
Please find out what your problem is and then I can fix mine...
Cant be electrical because we have had the plunger out of the stop control and it was still the same.does your alternator light on your clocks flicker because im thinking that its something electrical because iv ruled out pretty much everything you have?
The stop control is the only electrical part that could stop the engine from running.
Given up on it now as there is nothing else left to try
Ta, I'll check that again at weekend.
Got some injectors on loan to try at weekend, and will be checking spill off and return as well so here's hoping..
