As many of you know from previouse threads my 1997 300tdi discovery only travels one way, then the RAC have to bring it back.
Firstly broke down and found the cam belt arounf the bottom crank had stripped so only the crank shaft was turning. Fitted new cam belt did timing was running fine.
Shortage of fuel next, replaced fuel filter no better.
replaced lift pump stil same.
Removed fuel sended unit from tank but no blockage so fitted new fuel pipe from sended unit to the lift pump.
working no problem but over 50mph and hit a hill and it died in 5th gear, but will go up in 4th no problem.
Yesterday drove the 100 mile from my house no problem then it died, no fuel from the injector pump, did all the check on fuel supply, fuel all the way to the pump, pump turning over but no fuel to the injectors, gave it a blast of easy start and it would start but die when it was removed. Called RAC again to get me home, they did all there checks and said it was the fuel cut of soliniod.
To day went out and removed the black box covering the fuel cut off solinoid and removed solinoid to find plunger was stuck in pump.
Have removed plunger out of injector pump and refitted the solinoid hoping that it will prove that it was the problem but it refused to start.
so hoping for advise.
1. will the engine run with the black box covering the soliniod disconnected as I had to break it to get to the security screws so that it can be removed.
2. should it run with the plunger off the solinoid and the black covering removed
3. have I missed something of what is wrong and stopping it from running.

This is coming to the point of putting a match to it as it is becoming that much of a disappointement as car go, I have had many petrol range rovers befor and never given me any trouble, this is my first diesel discoverya dn it is a nightmare, desperate help needed please
 
I would avoid starting it with the solenoid missing-cause when it runs you are not gong to stop it without stalling or pulling the fuel pipe off the injection pump-probably not starting at mo due to airlock-be careful
 
I have replaced soliniod without the plunger on the end, loads of fuel and no air in system, I am not bothered about having to stall car as long as I knew it was starting and running, I would order new soliniod, the problem is that it will not start, and it is a fuel problem which is causing it not to start
 
Been covered before from memory:-
put the earlier type solenoid in and with a meter find the ignition live to existing solenoid black part-link to older style stop solenoid
 
The soliniod is not stopping the car from running as I have removed the plunger of the end and retightened the soliniod back into the injector pump. the problem is that fo some reason the injector pump is not giving diesel out to the injectors.
There is plenty of diesel, there is no air lock, atnk sender unit checked, new fuel pipe to lift pump, new lift pump, air fully bleed from system, timing belt ok, pump is turning, timing is ok, engine starts with easy start but dies when taken away as you would expect.
So my question is why will it not give fuel to the injectors and start

try the sedinmentor iv had the exact same problem ssl diesels can supply the new seals for around 2quid
 
There is no sediment in the fuel, new pipe, new lift pump, new filter, new diesel, plenty of fuel as far as injector pump, I have pumped that much fuel around the system that the diesel is coming out of the return pipe going back to the tank
 
crack the injectors 1 by 1 while someone cranks it over,too see if diesel is getting that far-I still reckon air and yes diesel should be going down the return line-where are you?
 
Are you sure there isn't part of the plunger still stopping fuel getting to the pump or other blockage-otherwise sounds like injection pump problem-I'm sure others will chime in
 
Hi, no part of plunger is still there, I thought that and I removed soliniod to check again, looks like I am looking for a secondhand injector pump, have done a search on ebay and most used secondhand are coming up around the £50 plus p+p, unless anybody on here knows a member who has one they are looking at selling.
 
If you can get a pump for £50.00 which works,that seems a bargain for an I/P-There must be a reason why your belt teeth stripped,perhaps the pump seized (or hydrauliced if the plunger went in running at speed then the shaft snapped under load-(is it a Lucas-famous for being weak in the bio fuel world-Bosch are considered bomb proof)-Maybe someone has a spare pump you could try before spending any money
 
I think the belt stripped because it was already starting to misalign and the outer edge had worn away by 5mm and had got caught in the casing someway, having looked further into the problem I read a webpage were this was a problem which was suppose to be corrected in a recall but I don't think they would honour the recall now, I am sure that you and your fellow members already know of this fault, me being new to discovery diesel world did not know. I think it is a bosch pump going by the erg control on the top of the injector pump as it says bosch on it
 
No I've only had mine a year,and no nothing of a recall-Very unusual for a Bosch pump to give up-Lucas are renowned for it-If it is a Bosch,I still wonder if is something silly-If you force it to run on easystart with the injectors cracked does any fuel show up(bit more omph than just cranking)-Might be worth a try
 
I have today been back out to car and removed fuel cut out soliniod, I cranked engine and fuel was coming out of hole that seloniod screws into, going to remove injector pump tomorrow and try to see if there is a blockage within the pump
