Is it one of the 'electronic' injection pumps or just a plain mechanical pump?

i think before the lever will work you need to make sure that the cam is in the right place or it feels like its not connected and not doing anything although i could be wrong.Also clean out the sedimentor which is fastened on the o/s/r chassis near the wheel.

All 300TDI FIPs are mechanical. What we are talking about here is how its controllled. Later ones have an ECU and are controlled by electrickery. Instead of having a cable from the accelerator pedal to the pump there is a potentiometer and some electrical magic going on. The poteniometers have been known to play up

its a 1997 on a P had a look has a cable but there is what id think was a pot on the pump

ive removed 11mm bolt from sedimentor and still cant get it off anythink else holds it on

colinl · Nov 8, 2009

there should be one 11mm bolt on the top of the sedimentor then its just a matter of working it loose as it sounds like its not been off for a while! you will need to make sure that the rubber gasket doesnt get ripped or you will have to replace it so it doesnt draw air.

right got it off after bit of tapping and pulling it fell off hit me and covered me in fuel. I clean it and when i went to re fit found small cracks in the top part ( where fuel pipes come in and leave). ive bypassed it and it drives fine anyone on know how much a new sedimentor is?

dont bother - its a common mod to remove them, so just leave it by-passed.

Ovaline Tractor oil from any Farmers suppliers or agricultural engineers. cheap as buggery and if farmers use it it must be good and cheap. or they wunt bother..
