    Cranks, No Spark No fuel pump

    Ok 2001 V8 Disco Delema. Keys lock & unlock. Engine turns over, No spark no fuel pump.
    Purchased new Nanocom. Prior to purchase tried manually resetting EKA code & checked inertia switch.
    Fault code reads-
    P1668 Anti-theft Alarm Serial
    link fault drive cycle A.
    occured 3 times
    Signal to high.
    My thought is BCM has passive immobilizer fault. not allowing fuel & spark. Where do I go from here?

    I once had a similar issue with my D2. This was before it developed a leak (since resolved) so no prospect of water causing issues. Turned out that nothing short of a replacement second hand Valeo BCU and then programming the keys to the new BCU would fix the issue. I don't know what the fault codes were but the symptoms were the same in terms of fuel pump. Would have been a bigger pain if had happened on a trip. Cheers
