In the end i had to take my car to the dealer to have the immobiliser ECU
reset. It only cost £80 and everything was OK.
thanks very much for the reply, i was starting to think that might be the
case after a day trying to start it and you have confirmed it for me much
appreciated, does it have to be a main dealer due to the equipment needed
do you know?
Not yet ! I tired changing the ignition switch and still not fixed – seems
like i may need to take the dealer to get what looks like an immobiliser
fault cleared.
Oh right im gettin no fuel come out of the little valve so im completly
stuck could it be a fuel filter problem
This connector under the rear right seat is a common problem on all Range
Rovers all the way to 2012. If your Range Rover starts having starting
difficulties, inspect and clean this connector. 90% of the time, this will
get her going again.
well my car still wont start – diagnostics pointing to “immobiliser” but i
will take a look at this connector and do a video for it. I think i will do
a video for the connector you are referring to also ! ( thanks loads for
posting up this advice ) Simon
I have the same problem as this and still cant solve the problem did you
fix yours?
Yes i think this must be a top level function that only the dealers can do.
We did try a few bits of kit on ours… snap on diagnostics and some others
but to no avail.
getplaning…….what connector under the right rear seat? I have a 2005
range rover 4.4 and it has no fuel pressure or injector/ignition coil
pulse, I can bypass the system and get pressure but the ecu still wont
command ground paths for the injectors/ignition coils, im leaning towards
faulty pcm since the abs/brake, battery charging light, air suspension
inactive
any joy with this as i am getting strange results. tried different relays
and testing wiring to pump but i think it has some sort of switched earth
to the bottom pin on the relay as i get 12v on the right pin, switched 12v
on the left pin, the top pin connects to pump ok, the only odd one is the
bottom pin which should be earth. i also have an immobiliser fault up on
the engine diagnostic on my allcomms software with nothing connected i have
4.3 volts at the pump with ignition off?? any ideas?
ok, thanks very much for your help, looks like a trip on a lorry for the
rangey
