Fuel pump probs !!!!!!

(1/3) > >>

ginge:
Hi there, first disco (200 tdi) and i have messed with the unKnown ! Tried to follow simple instructions on another site, on how to boost the fuel and tubo pres. Its now got no guts and struggles just to move, although the engine sounds as good as before. Have wound in screw (under cover cap) half a turn, then removed 4 screws to get at a rubber diagham (?) this is connected to a plunger which turns but will not come out. This goes through a splined wheel which i have turned clockwise about 6 clicks.

On the turbo side i have shortened the rod by about 5 mm.

Any ideas what ive done wrong or need to do????

Should have left it will alone as it was not bad before.

Thanks.

what way did you turn rubber bit sounds like you turned it way to far or anti clockwise and small screw under cap you should only turn after main adjustment to reduce smoke

Thanks for reply, turned the rubber thing 1/4 turn at first then tried lots of different positions, made no difference ! Are disco pumps diferent to defender ones ?

Disco Matt:
My advice would be to put it all back as it was (assuming you marked the starting position) then read the various websites thoroughly. That way you'll have a working car while you make sense of the instructions.

when you say eccentric pin did not come out how much force did you put on it? and you say you turned star wheel how so did you remove rubber or just hold it back
