Having a scorpion alarm / immobilizer on mine, mine sometimes doesn't cancel properly, and switch itself off, thus not switching on the fuel pump, so it starts, then cuts out. Most definitely the immob!

You using your original ecu, immobiliser box and chip kez?
yes mate

Coil Pack, Crank sensor?
midlands vw kindley leant us a coil pack to try but it made no difference , we thought the crank sensor mate at first when it would turn but not fire but now it is firing but dying so maybe not that ?

i still think immobiliser problem lol
:)

deffinitely immobiliser related...
try as a temporary fix, shorting the fuel pump so its got a constant ground and a constant live and then crank it, itll start and run then to confirm its the immobiliser system
anything is worth a try

my causin came down with his code reader but it wouldnt let him into the engine part , something to do with because the engine hasnt run there is nothing to read :confused: but if u are availabe after you get back anything is worth a try mate

Can you not take the crank sensor off your old engine, put on this engine, see if it does the trick.

Worth a try I guess?
