200tdi fuel system will not bleed.

Ive got a 90 with a discovery 200tdi conversion. ever since beening at a rather extreme angle whilst laneing the other day it is no no longer driveable due to having no power.

it will idle fine but as soon as you apply any load to the engine it will give up the ghost and stall out.

I am fairly sure its down to there being air in the fuel system, but try as i might i cannot get it out. now i thought it was a simple matter of running the engine, undoing the bleed screw in the fuel filter and letting it run until it starts passing fuel with no bubbles, unfortunately as long as i leave it, it simply will not bleed.

any help would be greatly appreciated.

also, i have replaced the lift pump as i thought this might have been on the way out but that has made no difference.

Open bleed screw and manually operate the lift pump with engine off until all air is purged

Also check fuel pump as they have a habit of just giving up and leaving you with no power

Yeah thanks, turns out i had been given a piece of mis-information. I had been told that it should self bleed with the engine running, turns out that was a load of cobblers, i had a large amount of air to pump out!

tdis will self bleed with engine running ,but may take some starting if theres too much air in system

Mine have always self bled, dont undo the screw with engine running.
If its playing up 99 percent of the time its the lift pump.

Mine self-bleeds in no time!!

Have you tried changing the diesel filter ? sounds like you might have disloged some crap in the tank

Depends how you go about it. If you change the filter and don't fill it up with diesel first then you will need to hand prime the bugger with the bleed nipple open. I've done it. Also changed the filter and filled it up with diesel and of course it will start and self bleed itself

Not realy as you should always fill a new filter up with diesel before refitting !

You should but you don't have to

Depends how much time you have to spare to try and get the fooker started afterwards

Well it didn't take me long at all. New filter on without diesel, bleed screw open, pumped it till all air was out and it started fine. Perhaps ten mins at most?

Yeah all sorted now, cheers fellas.

had fitted a new filter with out filling, i think i was just being somewhat impatient with the whole affair having not had it running for a few weeks!
