Give the bottom of the fuel tank .. a wallop with palm of your hand or rubber
Mallet,
And see if the lift pump fires up afterwards,

If so replacement lift pump time,

tried this but still no joy !! think I might just replace the pump anyway as I know its got diesel in the tank (walked to local petrol station 1/2 mile away and got 5 litres to make sure that wasn't problem)

starting to tear my hair out now lol

take the back seat out and remove the access panel in floor for tank fuel pump,check for power supply at the pump if there is the pump is knackered if not continue to investigate wiring etc.

hi I know its a stupid question but what position should the fuel pump cut off switch be in ? that's the little red rubber covered switch on passenger strut . also I don't seem to have power to the pump so was wondering if there is anyway to bypass the cut off switch?

[lozz]

It plugs in on two contacts by the look of it so.
Unplug and bridge with a suitable peice of wire or bridge with a fuse,

That's just to test mind, if the switch is faulty, I'd recommend replacing it
There identicle across the pug /Citroen range,

cheers lozz wil try it and hopefully that should be it (fingers crossed)

[chunk1973]

right I tried a bit of wire jumping the connections on the cut off switch and pump didn't work but I got a reading on my fuel gauge saying I was 3/4 full which I know is a lie as I only had about £10 diesel in the tank, so I have ordered a new fuel pump off of ebay from a bosch dealer for £116 hope this does the trick will keep you all posted on wether it works or not.

YES !!!! fitted new fuel lift pump model 0580 303 027 (2000 W reg fuel lift pump found on Ebay for £115.95 Delivered) and it fired up straight away and it was easy to fit as well ! THANKS TO EVERYONE WHO HELPED ME AND THANK YOU TO HAYNES MANUALS FOR MAKING IT AN EASY JOB !! hope the info I have supplied helps many others with the same problem.

Thanks again Everyone
