Hi to all. My first post here in spite of visiting the site often and finding so much useful info. I am on Freelander number 7 - all TD4's. My hobby is buying non running Freelanders and Range Rovers, fixing and selling them after a few months of use. All too often the reason for them being non runners is due to mickey mouse garages causing the problems.
Anyway my latest aquisition is a 2005 TD4 with 55000 miles on the clock. Bought it from an auction house with no description except that the engine does not turn - possibly seized.
So trailered to my house and tried to start it. No noises at all. No clicks or groans so I checked the fuse box and lo and behold - no starter relay. Fitted one and it cranked fine but no start. At least it was not seized..... Tried a shot of quick start and it burst into life and purred.
So leak back test and the diesel was pouring out of all 4 injectors with only the key on. This is very odd as with past experience one or 2 may be faulty and it never pours out. This could only mean injector damage for some reason - possibly dirty fuel. So after a bit of head scratching I went into the rear wheel arch and could not believe my eyes. The filter was not there. Some turkey had removed it completely. I am still shell shocked. So I fitted a new filter and then checked fuel pressures expecting to see lower high pressure numbers pointing to a damaged HP pump as well but all seemed ok.
I fitted a set of spare injectors I had and she now runs like a dream. All indications from my live data monitoring show that all is well. Perhaps the pump will start playing up in the future but for now its a fantastic car.
I drove the car a little before finding the problem and it threw up a couple of weird faults. It would drive fine for a couple of hundred meters and then cut out. The 2 faults it always showed were fuel rail pressure implausibilty and vehicle immobilised. The implausible fault was fairly obvious - not enough fuel pressure due to the excessive leakback from the injectors - but the immobilised fault had me confused till I figured that the ECU was immobilising the engine before there was pump damage due to lack of fuel. A red herring.
