TD4 Pump Change - earth lead.

Hi All

Changed my fuel pump and filter tonight in my 2005 Freelander. Bit of a awkward job but made easier by following info on this forum. The problem is when I first bought this car it was running real bad so I ran it straight into my local kwik fit type garage and got them to change the engine oil and fuel filter. I wasnt aware at the time what was involved with a Freelander fuel filter change. It took the guys 2 hours to fit the filter - and at one point had three of them working on the fuel filter!
Anyway tonight I saw the results of their work they had literally hammered the new Polish made fuel filter into its housing. Took a fair bit of removing. New filter and pump fitted but no sign of where to fit the earth lead! just found a single black cable with connector, guessing this is the earth lead. Where is it meant to connect?
Also found a a plug connected to nothing - anybody have any ideas what this is for?
Once all the parts was fitted (all OEM parts) car started great - took it for a 20 mile test run and it didnt miss a beat across all types of road. Parked it in the drive and 1 hour later tried to start - wont start. The lead Im guessing is the earth is not connected because I dont know where to connect it.
Any advice is really appreciated.
cheers all

Can you hear the fuel pump buzzing? Dodgy connector on that perhaps?

should be an earth lug welded to the body for the earth lead, they usually snap off, maybe kwik **** snapped it off and just wedged the lead to the body somewhere.

as for the connector with nowhere to go, was it there when you started ?

post a piccy, someone will know

earth-lug isn't welded... if it's snapped you need to ask your local dealer for part. It's just a bended bit of steel with a spade on one end & it slides into a slot cut out of the plastic tube thus making contact with filter-body.
Also, my '06 has that blank electrical plug just hanging to nothing

Thanks for the replys - When the car wouldnt start last night the pump was making a buzzing noise but just wouldnt start. Gave it a try this morning and she started so used it for my 15 mile journey with no problems. Same going home no problems on my journey home. Ive just gave it a rest for an hour and checked again, still starting.

When I finish work Sunday morning I'll drop the pump/filter assembley from the wheel arch and take some pictures hopefully somebody can advise on the earth cable and the redundant plug I have.

My trouble initially started 2 weeks ago, my car was driving fine. Parked it up to do some shopping - when I started my return journey up the A2 coast bound I found my car had turned gutless could barely drive up a slope or hill so I limped home. My first impressions was the fuel pump. RAC relayed it to a small garage Ive used before who specialise in German cars. The garage checked the pumps and reported the low pressure one was ok. I was told I had a faulty injector #3, and also a suspected faulty high pressure pump. Anyway when the injector was changed this brought up the pressure. When I paid the bill and collected the car found it still to be totally undrivable with no power. Ive already done the EGR bypass so decided to take off the inlet manifold and clean with oven cleaner using Mings guide. I also found the MAP sensor totally gummed up with black crap so looking at Alan C's thread decided to fit a new one.
By this time I had been getting the MIL light up and my cheap reader from eBay couldnt read my Freelander fault codes - RAC also tried and also failed. Fitting the MAP sensor cleared the MIL until the engine was started when it returned .
I phoned the garage who had changed the injector and told him my continuing problems suggesting the low pressure pump was going weak. The garage stuck by saying the LP pump was ok as they had tested it and said my high pressure pump was faulty and the car would have to come in for a new HP pump! I decided to get a mobile auto electrician to check the fault codes. The car was a non starter at the time of booking the auto electrician. While waiting for him I turned the ignition and listened to the pump prime, once it stopped I cranked the engine which started. Auto elecrician arrived I told him about the low pressure pump - he found no fault codes and said he totally agreed with me that the pump needed changing. As I said at the start of this thread changed the pump and filter.

My car has done 86k miles and Ive owned it 3 months.


While all this was happening my Mondeo TDCi also died with a knackered dual mass flywheel. That cost me £850 (DMF, Clutch, Clutch slave, Starter motor) - not a very good 2 weeks.

Thanks all - this forum has been invaluable during my Freelander problems

if you don't have a fuel burning heater the extra plug will be for a fbh fuel pump

Ive also a buzz in the engine bay of my car for the last month - checked around it tonight - its not the engine fans as they arent trying to turn - engine temp guage is at the 12 o clock position. Could it be my high pressure pump dying?
Cars still driving fine and just done another 30 mile round trip to work today.
cheers all

The earth lead has never been connected on my Freelander over the last 3 years, so I wouldn't worry too much about it

That sounds like the EGR solenoid buzzing.....

As Ive removed my EGR valve will this buzzing from the EGR solenoid cause any problems?

Since changing the wheel arch lp pump my Freelander has been running fine for about 600 miles now. Only thing Im concerned about is when my fuel level drops to just above a 1/4 tank my engine starts to get "lumpy" - this is at all speeds but especially slow moving traffic.
Could this be my high pressure pump playing up?

Hopefully fitting a synergy 2 next week so see what that does.

Thanks all for your replys.

Wouldn't have thought so as the high pressure pump wont know the level if fuel in the tank. As long as it get a constant supply of fuel its happy.

I would remove the combined sender unit/fuel pick up from the tank and check that it is clean and free of any blockages around the pick up area.

Yes, that's the starving duck. No doubt about, after stopping the engine it keeps going for some more seconds and then dies. T piece and peg is the solution.

Tee piece & peg?
Sorry to sound stupid but how would I do that?

Thanks

Well I removed the sender unit and found crap it. Cleaned out car ran great for a few days.
While this was going on I allowed the car to run low on fuel so this morning put £30 of diesel in from Morrisons - not much choice of garages here and I was low on fuel.
Drove about 4 miles and the car started to get real lumpy - decided to go on the M2 going home to maybe blow the crap out. Unfortunately debris was on the motorway and speed limit down to 50 mph. To top this when I exited all the traffic lights was out on J3 M2 causing carnage. By this time my car was cutting out - drove a few more miles then shen broke down in a real bad place - called the RAC and was given a 2 hour wait time - so carried on trying to start my car. Got it going and managed to crawl to my local Texaco - filled my tank right up.
Broke down 3 more times but got home.
Engine MIL was showing.
RAC arrived - he could get his fault code reader to read any faults
Also queried how long my wheel arch LP pump runs - its runs for a long time. It is a new OEM pump fitted 800 miles ago with a new fuel filter.
The RAC guy after hereing what I had been doing suggested removing my sender unit again and checking that it hadnt pulled more crap up.
After he went - didnt repair anything - I started the car and turned her around - shes running ok now.
Concerned about the LP pump running time what would cause that?
cheers

Ive just timed my pump and it runs for almost exactly 1 minute.

Pump cut out after one minute is normal.
I think I would pull out the tank unit and check for crap in the tank and pick up filter.
