2008 Defender 130 Puma 2.4 HCPU Alpine White

Replacing an ECM only, or replace matched ECM & Immobili

I am in the process of rebuilding and restoring a 2007 Defender 130 double cab pickup with a 2.4 litre Puma TDCI engine that has covered about 76,000 km in Sierra Leone, West Africa. This is a basic spec model with no key fobs or central locking etc.

The 130 suffered from an electrical fire in the engine bay destroying the wiring, all plastic parts and the ECU. Besides the fire, it suffered from a few years of neglect and poor maintenance. In the rebuild, have had the engine rebored and sleeved it (no oversized rings available here in Sierra Leone), replaced all wiring at the front of the vehicle as well as the ECU. The existing alarm immobiliser and instrument panel appear to be physically not damaged.

Engine and wiring are installed as well as a replacement ECM. The engine turns over with diesel going to the injectors, but it is not firing.

There is no working dealership with the electronic diagnosis equipment, so I am using a Nanocom Evolution to try and have parts “talk” to each other.

So far, I am not having much luck. I have read that the Nanocom does not have sufficient capacity to make a replacement ECM communicate with immobiliser, etc. Is that correct?

Does anybody have any suggestions? I am a bit of a novice user newby with the Defender but have used it a bit for work on Discos 2 and 4.

In my opinion you need key fobs matched with immobilzer. And the keys of course.

And I'm a bit surprised that somebody sells / buys a car without them - since it won't work without these.

Apparently, Defender keys are « naked » = made of steel + plastics with zero intelligence

They will never communicate with an immobiliser unit.
A luxury being reserved for the fobs.
