3.9 v8 not getting fuel

hi all im new just got disco back from mot yesterday went shopping right after mot but when i got back to the disco it would not start got it back home thanks to a m8 had a look and no fuel getting to fuel rail so undid filter at the back of disco turned disco over and no fuel comming out from pipe so put my ear next to tank as m8 turned key and it sounds like pump is working and one got any idear

thanks paul

no fuel in the tank cos its a v8. Maybe the pick up pipe on the pump is blocked

thanks for the reply how do you check the pick up pipe and just put £10 in petrol just to see it also runs on lpg but needs petrol to start

paul

i'm guessing here as i have a diesel, however if you can find the feed pipe ie the pipe that goes from the pump to engine, pull that off and and switch the ignition on and see if any fuel comes out(have a container to catch the fuel)

yer done that m8 as thought it mite be fuel filter theres just one at the back so undid that to put new on thought id see if fuel comes out and nope turned it over still nothing its starting to get to me now as not had it on road a day from new mot just had new mot yesterday and all i did was go round the corner streat after mot for shopping did shopping got back to car and dint start

paul

i believe there is a plug on the rear chassi rail for the power supply for the pump, i know you said you thought that you could hear the pump,however this connection can become dirty and not make a proper conection

thats great thanks as iv just had the disco waxoiled too have a look in morning as rain stops play

paul

ok had a good look today ie fuse realys fuel pump cut off switch and pump out found that the switch was up so reset and still nothing so pump out and the motor in the pump has burnt out seen some on ebay but one says with sender unit and out with out it what is the sender unit and do i need it

paul

If your going for a genuine parts fuel pump then the sender is part of the unit.

dont think its a genuine one but it looks just like the one i have fitted just cant see a difrance in the two pics on ebay thats why i thought id ask so just woundering what the sender unit is and what it dose

Measures the fuel level in the tank and provides the info to the dash fuel gauge.

ok thanks how easy is it to take off the old pump and swap over to new one

remove cover under boot carpet ,refit seal to tank before fitting pump/sender unit

yer got pump out ready to swap its just do i get one with sender unit or not and just swap sender unit over from old pump

paul

Just a point of interest, try holding the button on the lpg for 5 secs... it may well then start on gas

its a auto switch over wont do it till it revs over 2 000 rpm

Can u not switch from lpg to petrol? On mine it had a little button to switch back to petrol but hold it for 5 secs and it allowed it to start on gas.

yer m8 it has il give it a try but still need to get a new pump
