fuel problem

[iianorthants]

ooohhh just picked up my 300tdi and on way home it stopped pulling in 5th or anywhere above 50mph, has been sat in garage for and bit and as bank holiday they can't pick it back up till tuesday. has anyone had this sort of problem, it drives fine in 1,2,3,4 but 5th it just has no power like engine is being starved of air or fuel ?

think I sorted it...... drained the sedimenter and gave it a fresh tank of diesel and seems to be running ok  [-o<

[Guy90]

I was about to suggest that. Change the filter as well if it has been standing a while. Diesel goes off.

Yes as Guy says, definately a new filter straight away, also you can put some additive in the tank to help flush the crap out of the injectors and pump, if you drained any water off an emulsifier in the tank will get rid of that too

Then in a couple of thousand miles, for the sake of another fuel filter change it again, bit over cautious I know but better to be sure the system is clear and clean

Cheap as chips anyway, really not worth scrimping on. And that's from mister tight as a gnat's chuff. :(kerching):

cheap but not on a bank holiday  :(  had to buy from halfrauds but at least it runs better.

This is where buying in advance can pay off, stock up on your next service items, then get at least another set in at the same time. Including things like brake pads, wheel bearings, pro u/j's, prop nuts and bolts, locking plates etc

Especially if you are playing with them off road

You then dont get caught out so readily if anything like this happens, although if I remember you have only just got this one

Good ploy that one Kev. I always buy two gaskets at a time too. If they are pennies then three. Sods law if you dont, you'll make a pigs ear of something, have to strip it back down and tear the gasket, and it's always bank holiday sunday when you start these things. The shows are always good for that sort of thing. Bought 5 air filters for mine for a quid each at Langley farm. Better than the £15 they can cost EACH :shock:  at some "reputable" auto parts retailers.

went back in and had a new lift pump..... drives like a totally different car now, and does more then 60  :D

Just read the original post and was going to suggest the lift pump...
when you unscrewed/changed the fuel filter was it full to the brim?? i.e. spilled over as you unscrewed it??

If only half full (or more than 20mm from the top) then it's a sure sign that the lift pump is failing.

Hi just replaced the engine in my paperweight. Due to the replecement engine being slightly fire damaged, I replaced some of the bolt ons from the original.  This included the lift pump.  I then discovered that the new engine was from a sherpa (2.5 L Diesel), the old engine was a 2.25L.  I changed the lift pump because it was working fine from the old engine.  Now it is not pulling fuel through.  It primes OK.  I was thinking that maybe because its from a different spec engine the arm is not meeting the CAM correctly.  Any suggestions would be great as this engine change is taking forever now!  Another thing is I am getting lots of white smoke from the exhaust when running.  I have been told this is unused fuel being pushed out.  Would love a second opinion!  While I am here is it worthwhile changing the injectors from the old engine as I know they work fine?  They look the same, should they be compatible bearing in mind the different bore?

Here's to jumping in at the deep end!
