Hi all. Having been a bit of a lurker I always found this forum to answer all my discovery 1 300tdi issues. I'm afraid I have been finally beaten by my old girl and close to throwing in the towel.
To cut it short i nearly ran out of fuel on Saturday ( My husband always moans i let it run low)due to accident and roadworks making my 10 min journey nearly 3 hrs. Having put 1/2 tank in the old girl I primed her just to be on safe side and for the first time ever she struggled to start? The journey home was a complete nitemare nearly stalling at junctions and complete lack off power unable to get past 2000rpm.
She has me stuck I have changed fuel filter, fuel lift pump, cleaned sedimentor which was horrible, a new start/stop valve on injection pump. Now she won't start at all unless I fill up the fuel filter every time and when fuel has ran out in filter she dies so I know it must be a feed problem from the tank or is it something else?
I went to change sediment unit today but my return pipe is a 3/8 wtf and connector is shot so going to replace the pipe with 10 m and a new sender unit. I just don't understand what is happening. If this work fails have I missed something. Any help or previous experience with this problem would help me loads. A female who kind of knows my way around a set of spanners so all answers welcome.

I recently had a fuel starvation problem on my disco1, after changing fuel filter, cut-off solenoid, by-passing rotten sedimenter, renewing lift pump, the fault was a pinhole in outlet pipe on tank sender unit, the effect was===starting no problem, general drop in power, stalling after covering 600 yards, then firing up straight away, if revs dropped below 1500 for more than 1 miniut it would it would lose power again, I found the problem by seeing diesel dripping from bottom of fuel tank, I took a look at the fuel sender, it soaked on top with diesel, all pipes looked good-ish but there was pin hole in outlet pipe underneath where I could not see, I would now recommend searching for problems starting at the tank.
 
Have you checked the pick-up pump ?

Disconnect the pipe that goes from the pump to the filter, remove the fuel cut off wire from the back of the injector pump, then crank the engine. There should be a healthy pulse of fuel from the lift pump.
 
That's on my list of jobs tomorrow with a possible tank flush aswell. My husbands thinks I blocked a line somewhere as for love nor money I can't get my fuel line to bleed via the fuel filter bleed screw. There is just no fuel reaching my engine.
 
Yeah changed pick up pump making sure I was over cam and not under also used new olives and nuts even though old ones looked ok and used both new gaskets and smeared with hymerla blue. Pried lid off boot floor to sender unit and although full of crap there was no fuel visible but I have a new unit to fit tomorrow. Do you think it is some crap blocking my lines then?
 
i had **** blocking the lines on mine before, took the pipe off the lift pump and used an airline. 150psi sorted it no bother :)

Yeah sounds like it, I can't remember if there is a gauze filter at the tank end :eek:

As bunny says give it a blast back down to the tank - with a footpump if you don't have an airline ... cheap option innit :D :rolleyes:
 
Have compressor for blowing lines. Just a quick female question sorry if it sounds dumb but can I blow lines if still attached to sedimentor as unable to disconnect because of corroded fixings. Just worried air would cause another blockage or should I remove sedimentor bleed screw first. Just don't want to get it wrong. And I'm missing having the old girl terribly.

Get a new one they're not big bucks ...

Landrover Fuel Sedimenter | eBay

and they do catch the crap/water from the tank ...
 
Quick update. The old girl is running sweet again. Happy days. Used compressor to clean lines and omg the amount of crap was unreal. Fitted sedimenter another new fuel filter fitted. Reprimed and she fired up as good as gold. Took her for spin around the country lanes and she has more power than she ever has since owning her. So a big thank you for all your help.
Plus I have lots of new shine parts on her. Won't last long though.
