Thought I'd add some content to the site which has helped me several times before...

My Seicento Sporting comprehensively failed to start after several years of relatively trouble free motoring so I consulted this site for more information. Several solutions to similar 'non starting' questions focussed on the TDC sensor as being the problem so after a bit of thought I ordered one from the local supplier. £26 and a short train journey later I had the part (Italian made, not generic Chinese).

An hour later the car was running again.

So thanks to everyone on the site for helping me out again - so much more informative than what's become known to us as 'the book of lies' (Haynes).

Splendid!
