Can you tell us what the immobiliser light it doing? Does it flash when you turn the key or stay flat red?

Usually when these cars are left for a while the ecu/immobilisers do funny things

it's turning over then?.

had this a while back needed a new battery, mine wasnt turning over though.

have you tried disconnecting battery and reconnect

 

[silvercup172]

[silvercup172]

Will it bump start? Or start with jump cables?
