Maybe worth checking that engine oil is not over filled and also change the crankcase breather filter.

When testing for a live feed the front pump must actually be running. It times out after a minute. Check you are testing against a good earth. There is an earth header for the in-tank pump behind the RH side panel near the tail door hinge.

The other pump is in the fuel tank combined with the fuel gauge sender. You should check if you can hear that one running at the same time as the under bonnet pump. There is an access plate under the rear seat.

I think you've sussed it. Both pumps should run together at ignition on, so your findings suggest the in-tank one has failed if it's only the under bonnet pump that's running.

did you read post 7? you didn't reply

Satisfy yourself that it's the pump don't take my word or anyone else's. i'm not responsible if it's wrong.....;) Use only genuine LR pump, cheap pumps are crap and noisy, well documented on here....part number is LR023043. search online for best price......... link to guy salmon here...

Filter 60k or 5yrs so should be ok then. Pump could still be tired, the fact it runs doesn't necessarily mean it can deliver at required rate. There should a be fault code stored so you have the option to go for a new pump or have codes read first.

does it have good service history? fuel filter changed recently? very possible Lp pump faulty.....

Tyre noise maybe??

So if you rev it when stationary does it then just sit at 3000rpm missing and spluttering? What's the mileage?

BTW that coolant sensor is the one in the coolant elbow with 2 wires......I think it's blue...

I wouldn't stick my neck out and say anything will definitely work. The problem is the older the vehicle the less compliant they are with anything other than LRs own 'Testbook'. There are other professional code readers may well work but the price dictates only pro's can afford them. A Hawkeye...

Apart from checking for obvious problems with any of the sensor connections and checking the injector pump harness connection there's not much point in guessing and you should get fault codes read from the ECM.

I can't think of any reason why this would cause increased fuel consumption. It could be coincidental and due to falling temperatures.

Aye yer right there were reports that a few people had used this new pierburg Maf on Td4s but it appears that Ron has tested one and found otherwise. One thing though as regards you assumption that you Maf is knackered, if you disconnect it and there is a marked improvement in the way the...

You need to be more specific......which pump? any work done recently? pipe connector come apart?

Yes it needs a small washer that fits on the tip.

eeerrrrrrrrr wouldn't like to say, only ever used dealer parts. Is there a huge difference in price?

:confused: If your referring to the Lp pump it just stops working. If you mean the Hp pump then yes they have been known to leak some when cold reducing/stopping as the pump body warms up.
