Charge the battery to full and check the inertia switch to not be unplugged/disturbed or tripped... the immobiliser has nothing to do with that cos immobilised = no crank

to which ECU? did you try to access all of them and no comms at all?

Charged battery to full, checked and reset inertia switch then bridged to check,
Thing is it still cranks so only half dead? . So yeah not immobilised but sort of?
I'm not very clever with nano coming only learning but , it powers up but don't connect

Oh maybe I should mention , I de aced it a little while ago but had no probs after that apart from the ace light being amber, would this affect it?

did you try to connect it to SLABS or autobox ECU too and you get the same message? ACE has nothing to do with that...if the pump doesnt run are you sure is not dead? what if you bridge the pump relay? cand you hear it then?

Bridged relay and pump ran so no prob with pump.
I guessed ace would be OK, I'm trying to learn what the body control unit does it seems to do alot thought it might involve the ace too
