Hi,
Just moved to South Africa from the UK, I bought a 2002 Freelander TD4 as a run around even though I was warned not too by many people - I should have listened. I have experienced a raft of problem which have all been solved with my own knowledge base, I won't bore you with these tonight, however the final one is causing me serious mental strain. Tomorrow I will be John Cleese with a stick giving the car a whipping if you cannot help
I bought the TD4 as I am very familiar with the M47 engine having owned an MG ZT CDTi and tuned it well! I thought I could fix all issues on diesels having rebuilt vintage Lister diesels and having automotive electronics experience along with intermediate knowledge on common rail diesels.
The problem....
The car requires "winding up to start" when cold (20+ centigrade so not glow plugs!) this consists of some 5-7 seconds of cranking before it "catches", across all 4 cylinders.
In the first week the in tank pump became noisy and failed, the car had been difficult to start and I assumed this was the problem. After being quoted £450 by the independent Landrover dealer I bought an aftermarket unit from the UK and imported via UPS and fitted it yesterday thinking it would fix the problem.
This morning I went to start it and the same symptoms presented themselves 5-7 seconds cranking. When warm the car starts without issue but degrades the colder it gets. I therefore went through the usual suspects as follows:-
Bought a new battery just in case as the other one failed after <1 minutes cranking when testing
Checked wiring between HP fuel pressure sensor and ECU pin to pin - no resistance.
Checked HP fuel pressure (as stated on this forum)
"Connect multimeter between battery neg and blue/black cable (connector clean and pushed firmly onto HP sensor, you will have to probe into the connector)
Ign on (position 2) 0.5v approx
Engine idling 1.3v approx
3000 rpm 2.0v approx "
My results Ignition on 0.5V - Idling 1.3V spot on to the above results!
So I thought maybe low HP pressure when cranking, no problem here - with the cam sensor disconnected and cranking I got 1.3V indicating no injector leak back and no problem with the HP or LP pumps.
The car has done 122,000 Km's (76,000 miles) and has full Landrover service history. Performance is fine and no apparent burning of oil so I cannot believe its low compression but remain open minded.
I guess I could take it to the local "stealers" and put it on the testbook but I am not sure this would tell me anything (standard eobd reports no codes)
So please save a Freelander from a whipping and help me out!
Thanks in advance....
