Hi All

Looking for some guidance and advise around my 03 Plate TD4 Freelander.

Its been off the road for a while as I needed to replace the clutch which I did yesterday, however prior to this I was having some issues with Warm Starts and powerloss

The powerloss occurred at any stage whilst driving it would simply drop the acceleration never fully cut out but a significant drop of power.

The hot/warm starts seems to be whenever I have jumped out and turned the car off if i try to re-start within 10/15 it simply won't start. I have tried to do this with jump cables on battery boosters all sorts but no idea?


Could anyone offer some advice? I am an almost capable tinkerer so if someone can advise what to tinker i will delve in.

Thanks Guys and Gals

Power loss could be a copy of things. Low pressure fuel pump on its way out or faulty map/maf sensor.
Warm start issue is usually the crankcase position sensor needs replacing.

MAF sensor, left hand side of the air box, there's a connector on top, unplug it and see if the car runs better. Doing this will run a default value for the maf.

MAP sensor, left hand side of inlet manifold, little black box about an inch by half an inch. Unbolt it, clean with carb cleaner or equivalent. Do not stick anything down the little hole apart from cleaner. Plug back in, see if there's a difference.

Crank case sensor, don't know!! There have been discussions about this, try a search. Or someone else will post something.

Sorry, forgot the fuel pump.
Under rear wheel arch, drivers side.
If you don't know when it was last changed, replace pump and filter. If you have replaced recently just change the fuel filter.

Usually the hard to start problem when the engine is warm would be the camshaft sensor, best way to test this would be to get the FL going from cold drive round the block get engine hot park up out side you home turn the engine off, then wait as you would when it as been giving you trouble if it will not start remove the camshaft sensor stick it in the freezer for about 10 minutes refit and see if the FL starts if so you know camshaft sensor is at fault.

03 plate. Low pressure fuel pump is under the drivers wheel arch, behind the plastic guard.
High pressure fuel pump is in the engine bay.

That's the earlier one

As Mike said yours is under drivers side rear wheel arch
Turn your ignition on and you should hear it buzzing
 
Thanks Mike, that's cleared it up for me. Having had a Rover 75 and MGZT for a number of years I'm use to the fuel pump being in the tank. Whenever I've done a search for a TD4 fuel pump the one in your link shows up and I'm thinking that's the one in the engine bay so I'm still looking for the in tank pump which I'm finding, then I'm told it's under the wheel arch adding to confusion. Anyway cheers mate.
 
On a later 2002 onwards Freelander, there are 2 fuel pumps. There's the rear lift pump which is under the driver's side rear arch, along with the filter. The only other pump is the High Pressure Fuel Pump or HPFP. This is on the engine, driven by the cam shaft. It's job is to raise the pressure from the lift pump from 40-50Psi to the 10,000+ Psi needed by the common rail injectors.
As yours is a 2003, the lift pump will be the in line later type under the rear arch liner, as linked by Mike.
 
Mines actually a 2005 I just tagged along on this thread. I wrongly assumed the setup was the same as the R75 with intank and remote pump in engine bay. I'm with it now thanks for your input guys.
