Please Help !!!! Im new and have a mega fuel cons problem with my freelander

Hi all !

I'm new to Landy Zone today, hello to you all, well new member but I've used for information in the past and found you all sooo useful! So please go easy on me!

I'm am desperate to find a solution as I have a mega fuel consumption problem with my 53 plate freelander td4 auto and am now very desperate to fix it or she has to go!

A little history, I've had it 3 years in jan, So far, replaced;

Turbo
2 x injectors - starting problem
alternator
battery
New back diesel rear fuel tank pump and filter 6 months ago
Main high pressure fuel pump reconditioned twice as seals blew out
Oil changed 6 months ago with a decent one
just had EGR Valve cleared
New engine breather decompression limiter valve and filter
New brake pads to check none binding

I keep the tyres at 35psi as just me and my 5 yr old with no excess luggage on board and check tyres regularly
never use supermarket fuel


I recently had one of the two above injectors put in due to a starting problem which the garage diagnosed as injector and when i picked it up it was going flat at 30mph which usually its about that point that it boosts.

I took it back and they removed the KINGQUICK? it had on it from when i brought it.

I have very limited knowledge on this box, which i understand pumps more diesel into the injectors? Well all lights were on the box but as I said my knowledge is very limited on this.

They say it was confusing the computer or wasn't working properly.

It now runs ok but just a little more sluggish but I drive pretty sensibly so didn't really make a difference to me but.............. as for my mpg...... well

After leaving the garage I put in just a tenner to see how much difference it made without the kingquick on it and I was pleasantly surprised as I got out of it what I would usually get out of twenty quid so I was looking forward to the difference...... well

Two days after this...

Now I am averaging 13.37mpg!!!

Its crucifying me and if I cannot get to the bottom of it I'm going to have to say goodbye which I really do not want to as I love it.

I've tried using injector cleaner twice but no difference.

If anyone has any advice or knowledge everything would be so very much appreciated as I'm banging my head against the wall and very desperate.

I have done a little research on the Kingquick box and understand its a maf compensator? if I am correct, rather like the synergy, does anyone know of a way of testing the box to see if working correctly and I can have it re-installed, or how long these boxes last for, I'm worried that it was because of this box the seals in my mhpressure pump blew so left if off when the garage removed it.

Once again any advice would be greatly appreciated !!!

Hi there im new on this site aswell just been reading wat ya saying about ur landy i had the same problem wit my 90 i i found that the injection pump was finished and i replaced the lift pump hope it helps

Hi there

Thanks for your reply and hello fellow newbie!

Sorry if I sound a little vague but the injection pump you speak of and lift pump are these one and the same thing or two different pumps

I replaced the rear pump located under the back wheel arch along with a new filter around 5 months ago and had my main high pressure pump in the engine bay, re conditioned after the seals blew a few Months ago, please tell me its one of these and there isn't anymore pumps in it!!!!

surely a diagnostic check would flag the fault up?
