Firstly i would like to say hello to everyone as i am new to this site...
I am the proud owner of a 2005 Convertible in the UK. I love the crossfire and find it the most reliable car ive had...Saying that, i have a problem and would be very greatful for any advise.

The other day i started my car and literally drove off as the thing fired up.
This caused the car to drive about 5 feet then die. The spoiler raised also. It started 2 more times but engine just died straight away. The car will no longer start.
I called out a mechanic and he checked the starter motor etc and thinks it maybe the immobiliser. When i turn the ignition key everything works perfectly with no power shortage. The car will just not tick over.

I have tried all the various techniques mentioned on here but seem to have no luck. I am really reluctant to take it to the main dealers as in the UK this really does work out expensive.

Any advise is welcomed.
Many thanks
BC
