Thread: Troublesome TD5

Here are some things you may wanna check.

Did you get an ECU with the engine or are you using the one of your old motor, as it may be from a later model which has a different ECU fitted, earlier were solid state and later were flashable with different injectors etc. And I have heard you need to punch some codes into the ecu's when you change them over it's just not a matter of plugging a new one in. I would call TRS in Adelade they are quite helpful with things like this

The motor came with a ecu, but being from the wreckers you never know if it is the correct one.

The motor is a 99 model so it is a early td5.

Is the replacement engine/ecu from a Defender or Disco? If from a Disco it will be expecting to communicate with the BCU (body ecu) and immobiliser.
I would use the original ecu unless you know the replacement ecu is from a Defender. The original will require the injector codes to be corrected but it will still run in the meantime. The injector types should be the same as from your signature your original is a 2000 model - still an eu2 engine.

Thanks, I will change over to the original ECU.
The other problem I have encountered is that the middle injector has a smaller size spring and fitted with a green collar on top. I subsequently replaced this injector with one from the original motor (which has five injectors that are all the same including spring size) however the bore filled up with fuel when I cranked it over. Any ideas.
Thanks Ben.

changed the ecu but still no change,

Have you had any luck yet?? I am about 20 minutes from you and have a rova com lite that may give some info on the problem and fire the injectors manaully to see if they are working. checked the position sensor on the bell housing may have unplugged with movement??

Hey stevo,

No luck, any help would be greatly appreciated.
Cheers Ben.

also they can take alot of cranking to get the air out of the injector fuel circuit
