White Smoke Woes!!

Right, back again! See my previous thread http://www.landyzone.co.uk/lz/f8/me-again-93296.html

Problem is still there. Cambelt changed and timing checked, all fine. #1,#2 and #3 injectors swapped for known good one, and fault still apparent. Could not replace #4 because the injector used to test the others is not the electronic variant as found in the EDC engines, and with a 'normal' injector in it would not start.

My next move is to remove the injectors for proper testing, and if poss get the #4 checked for the sensor operation (pressure I am led to believe?). If they all check out, then my next move is to whip the head off and have a gander inside to see if there is any obvious nastiness going on in there. If I find nothing visually, then I may well get the head pressure checked too.

In the previous thread, the problem came on after around 3-4 minutes, now it happens almost straight away. I did think of getting a guy with a computer to check it but he doesn't seem to think the early engines give much useful feedback.

Any advice/opinions/suggestions received with thanks

had a similar kind of problem on a mitsi 2.8 engine, used to start fine and run for about two mins then judder to a halt, after hours and hours of investigating turns out the front seal on the injector pump had started leaking and was putting fuel into the oil, so as a temp fix till the weather warmed up i put a litre of petrol in the fuel tank to expand the seals a little, it was a bit of a job to overhaul the injector pump and re-fit and didnt fancy doing it during the winter, the petrol worked (for about three weeks) so then i put on an electric fuel pump cos the injector pump didnt have enough vacuum to pull the diesel through. good luck anyway hope you sort it.

Well, finally seem to have nailed down the problem (I hope!). After getting a computer diagnosis done, 4 faults showed up, 3 cleared but code 9 (speed signal sensor) remained. It seems the pump isn't advancing with the throttle pressed. Apparently, the crank sensor is responsible for instructing the pump to advance with engine speed.

So, I duly set about removing the sensor, which on the auto is situated in probably the most awkward damn place possible. It sits on top of the bellhousing at around 11 o'clock when viewed from the front. I finally got the bolt out, but on removing the sensor, the actual part that sits inside the casing decided to play homesick and stayed put!

So I am now stuck with the middle of the sensor firmly lodged in the casing. If anyone has any ideas then please feel free to air them. It took me around 45 mins just to remove the single bolt from the sensor because it is so awkward to get at.

As a last resort I think I may have to drop the gearbox!

Any help gratefully received
