Hi all new here. reposting this in this thread as not sure if first post was the right one.

On turning on the ignition on a visit to my mum there was a load banging noise from the rear of the freelander( 2003 td4 ). Started up and ran fine for 30 miles and then started intermittently going into what I think is known as limp home mode especially when going up an incline. Almost made it home when management light came on and I parked up in a very convenient layby. Wouldn't restart.

Recovered to a garage and had new rear wheel arch pump fitted & filter.
Went to collect it didn't start quite as nicely getting progressively worse over next three days when foot down and lots of cranks just got it started to get me home. Wouldn't start again.

I can hear a sort of cavitating whooshing noise from the region of the hp pump on prime ( first click on key ) so I thought drawing in air maybe from tank. Pulled up carpet and undid connectors to tank and attached temporary hoses to feed and return. Switched on to prime and had fuel delivered to both inlet and return pipes ????????????? Went with one gallon of fuel and came away with two before I realised what was happening.

So two questions 1. Air whooshing noise in hp pump
2. Fuel coming back inlet pipe to pump and where's it drawing from.

Utterly confused
Thanks

So are we.
Please explain a little more about what you did with the pipes, as if fuel is delivered into the Injection pump supply pipe, it will run through it and return to tank via return pipe, so not quite sure what your getting at.

Someone seems to have the same confusing problems here http://www.landyzone.co.uk/lz/f57/non-starter-weird-fueling-263975.html

fuel pressure sensor or whatever it is called on the engine?
check for corrosion in the contacts.

hi
borrowed this pic from the interwebbynet. start at one end so high pressure pump pressure a good place as you have fuel flowing round. having just replaced the pumpon my own battle wagon i went through all this. wooshing noise is more than likly just the fuel circulating on ignition on it circulates constantly through a cooler to keep the pump cool. voltage figure needs to be close to the one stated. the system needs 12000kpa before it has a chance of starting. yup that 1700 ish psi. also the voltage should rise quickly not gradually the best way is to have a diagnostic pack and watch the actual reading of the pump in real time but the voltage method will give you an idea
