OK, I have replaced the transfer box oil seals and refitted whilst I was waiting for the new seals I decided to whip off the red plug on the eng ECU to check for oil contamination, thankfully non there.

Anyway, put the box back on and went to road test it and it fired up and ran for approx 3 secs(in that time it can also be revved).

Removed the engine ECU again to check for plug and pin damage, all seems ok.
Mate called round with TestBook (ex rover tech) and it appears theres no communication between the BCU and eng ECU so it's not getting the signal to mobilise ECU, tried getting T/book to foce engine code and it couldn't so my next job is a continuity check between pin 34 on C0658(eng ECU) and pin 10 on C0661 (BCU).
Just wondered if anyone had come across this before as it was fine until I refitted the transfer box and checked multi plug on eng ECU for oil.
Oh yeah no faults in engine ECU!
Thanks
Chris

have you tried entering your EKA code in the drivers door lock ?.

MMMMM, no but I didn't have it until my mate connected his TestBook so may try that tomorrow just to see if it starts!!!
One of the codes is 13, think I should give my wrist a rest tonight:screaming_bug_eye_f
Cheers Del!

SORTED
Theres a green and slate(grey) wire between the BCU and ECU that carries a signal from the BCU to tell it that it's happy the correct key has been used, the BCU waits approx three seconds after engine start up for this signal and if it does not get it the engine will cutout and you'll have no faults stored in the ECM.
On mine someone had fitted(badly) a new black plug on the ECM and the wire broke off the pin in the back of the plug!

glad the repair section worked out ok.

Big thanks to Mad Hat Man for supplying a quality new ECM wiring loom at lightening speed and a very reasonable price.
If anyone has any cabling needs he's ya man!
