Hi all, hope your XMAS went OK (can't be worse than mine is at this moment in time 
)
I have had major issues over the past year (don't ask why so long) with our 300TDi Auto Disco. The basic fault was very rough running and tons of white smoke (unburnt diesel) out of the tail pipe, enough to get me instantly arrested if I were to take it on the road
Done loads of stuff to try and cure it and in the end gave up chucking money at it and decided to change from the EDC system to a normal a cable controlled throttle Injector Pump. Spent the last couple of days replacing the EDC pump with a non-EDC one along with the injectors and feed pipes.
I need to extend the boost pipe from the turbo take-off to make it reach the IP but this will not give me the issue I have at present (if I am correct).
I eventually got the engine to start, I have no throttle cable at the minute as I have got to get one but I wanted to see if the original fault had been sorted (no advance of the IP basically so fueling at the wrong time).
The other thing I am missing is something that should fit into the top threaded hole of the pressure compensator in the top of the IP. There are 3 connections as you look at it from the rear of the pump:
Bottom one goes from the leak-off on #1 injector, middle one is the connection that will go to the take-off on the turbo, and the one at the top which at the minute has nothing in the threaded hole. I do not know what should fit in there so am not sure if it is causing my issue.
The problem I have is that although I got the engine to start after much turning (no fuel in lines so took a little while) the engine started fine but then the revs rose and kept on until they hit the max with the engine revving it's ar$e of My first thought was the turbo feeding oil into the inlet and I was waiting for the engine to destroy itself!! But I disconnected the lead I had running from the battery to the stop solenoid, (just a temp measure until I can find the right cable in the loom), and thankfully about 5 seconds or so the engine stopped. It still turns over OK but I am not going to try and start it again until I get some more info. I am assuming it is not the turbo causing the engine to run away as it stopped shortly after taking off the stop solenoid feed wire.
I would really appreciate any help or advice here, either on a possible cause, or what should be connected to the top hole on the compensator on the top of the IP.
Thanks in advance.
