Hi All,
Recently joined up after using the great wealth of knowledge on this forum for the last year or so as a guest.
Work undertaken in the last year on my 2003 Freelander TD4 includes (and probably won't be limited to):-
New turbo
New cylinder head
New drive shaft to NS (front left wheel)
Internal body repairs to rear floor pan
Starter motor overhaul/rebuild
and so on.....
Current issue I have is:
After completing the cylinder head and turbo change everything is reconnected and oiled/sealed as it should be. Problem is that it just won't start. I have been through all the threads looking for a similar set of symptoms but so far haven't found anything of use - unless it is the often cited ignition switch failing. Others have mentioned the ECU and key being out of sync, but that would suggest that the immobiliser would remain active, whereas mine appears to disable correctly.
The alarm fob unlocks the doors and the immobiliser light stops flashing. When I put the key in the ignition and turn it to the second stage all lights come on as they should. All electrics work (new battery just to be sure) I can hear the fuel pump working to prime the system (it runs for about 30-45 secs) and know that it pumps fuel to the injectors. However, when I turn the key nothing happens. The clock (telling the time) dims and that is all. The immobiliser light never flashes.
I have checked the connections under the bonnet and can turn the engine over if I connect the start directly to the battery to bypass the starter relay. However, I can spin the engine for 30secs but it still doesn't fire up.
I have checked all wiring connections and am confident they are good - eg used ammeter to check starter cables and points. I know the starter is good by itself, so clearly it isn't receiving a signal from the ignition perhaps due to the immobiliser as the wiring diagram would suggest.
Similarly, it would suggest that the glow plugs aren't being heated to ignite the fuel when spinning on the starter because of the immobiliser- or do I have this wrong?
Any thoughts on this are welcome as I know it's been heavily discussed. I have described the situation as best as possible, but please let me know if I have done something wrong or am looking in the wrong place trying to solve this problem.
Thanks
