Eventually got the pesky little bugger out using a friends 8mm torx socket. I guess mine wasn't a good make! New CPS fitted and she fired up first time. Left her running for a couple minutes. Turned her off for a couple and went to fire her up again and... I hear a very pleasing noise of engine 😎

A big thank you to everyone that contributes to the site and for providing the solution to help me get my car back on the road 👍🏻
