Hello @kevstar :D:D:D:D:D!!!!
I did think about sniffing the exhaust but somehow while posting, or eating me tea, I forgot. Also forgot that of course the IP would be able to pump up enough fuel, so lift pump not really the issue.
He said it smoked "white" hence my worries about water vapour so gasket or worse cracked head methinks, also my Qs about coolant and oil levels.
Looks like we both are thinking along the same lines except for the governor/pin issue.
Be interesting to see what happens with these monkeys who know how to rack up the hours for nothing!!! Or maybe OP'll get it out of there!

Interesting alright lol.... I bought a project 300tdi from a garage who couldn't get it going & they were charging the poor
chap a fortune so in the end he gave in an got them to sell it (to me) I got it here & had it going in 20 mins plus 10mins
of that I was looking for fuel :rolleyes: These new age garages with all there diagnostics don't have old skool grease monkeys :D

Anyone thought of a delaminating turbo hose, blocking off and starving the engine of air, white smoke can be unburned diesel.
@Tomperks needs to get his Disco out of that "opportunistic" workshop who's going to bleed him dry faffing about the edges.
Things like IPs and fuel system issues don't immediately fail, running ok one day, not the next.
 
Hi guys, I've rang the garage today and told them to scrap the idea about checking the fuel lines at this stage. I managed to pick a recon Injection pump up from a mate for £260 so that's going on Monday/Tuesday and we'll see what that does. Seems really weird that as soon as the IP was touched then the issue began so for £260 its worth changing anyway. Plus it looks like it's seen better days, clearly it's been messed with a few times over the years!! How long should this take to change? The garage are telling me it should take 4 hours to change the IP and cambelt. If that doesn't work then I'm going to get them to do a compression test and run a gerry can to cut out all the fuel lines.
 
Four hours doesn't seem ott to me including the timing belt just make sure they fit a dayco one and change the seals in the timing cover.
Just out of interest what's their hourly rate?
 
I have had exactly the same problem with my 200tdi, wouldn’t rev pass 2.5k, done all the usual
Fuel filter/ lift pump/ Sendimenter, checked turbo boost and timing all to no avail,
As the injection pump has its own lift pump built in I ran a direct gravity feed to it
With no improvement,
So that’s leaves the injection pump as the culprit, so out it came with the injectors and sent
Off for to be refurbish,
I had my Discovery new in 1990 and know that the engine is sound compression wise and didn’t
Burn any oil and assumed the 12 year layup had caused corrosion in the injection pump,
Why the suggestion that the lift pump is the likely culprit for loss of power when the Injection pump already has its own I think is misleading, the only scenario I can think of is a blocked fuel pump/ supply or split diaphragm causing air to be drawn in before the injection pump,
Just my 2 cents worth, it may be of interest to someone,
 
Hi guys, I should hear from the garage tomorrow - There finishing off the cambelt tomorrow morning, the pump has been fitted. I've read a few different stories about the immobiliser on the 1994 Disco 1 and failures. Just after the rev limiter issue and lack of power, the stop solenoid stopped receiving power from the relay (intermittently) I wired a cable from the battery to it and it starts first time. I'm wondering could this failure be caused by the immobiliser, and could this issue potentially cause the lack of power/rev issue? Or are the two issues completely separate.
 
Hi guys,

The car has come back from the garage and I've now had it back about 3 weeks! The issue was a stone in the fuel tank, blocked sedimiser tank and blocked fuel lines.

Have they tried jury-rigging a gravity fuel tank direct to the FIP and testing it like that? That would rule out fuel pipes, sedimenter, filters the lot, really quickly.

Id use a gallon can & use a outboard primer straight onto the IP

Sometimes "old skool" actually does work. Did they tell you what made/helped them find the stone in the tank, etc?

Still find it hard to believe that the truck ran OK when you first got it then didn't. Who puts a stone in a fuel tank for F's sake?

Don't actually remember you saying The IP had been touched at all anywhere in the thread and no one else suggested it could be the problem, if anything the reverse.
So looks like the garage was right all along and just charged a lot to get to the bottom of it.
At least you have got a few more new or refurbed bits on your Landy!
Do enjoy it now, your first Disco will be a learning curve, mine certainly was!
Do also get on top of the rust in the rear wheel arches, the sills, front inner arches and the rear floor if they have not already been done. I only touched these and this is now keeping mine off the road, stitch in time and all that.
And come back to us, much useful help on here, I know cos I've had to use it lots!
All the very best!
