Hi, I'm new to the site, so nice to meet you all!
Anyway can anyone help? I have a 1990 S2 turbo which sometimes will not start, turns over but no spark. As soon as you let go of the key you get a spark! Ignition is fine normally, and if you push start it it runs no probs, but whilst turning over there is no spark. Whilst in this state, when you let go of the key the fuel pump has been enegising (Like it does when first turning ignition on) 3 or 4 times in a row, once it even stayed on pumping until I turned off the ignition!
I have changed the ecu, and the coil but other than a loose connection which I know will be a bitch to find, has anyone had this fault?

Cheers for any help
Chris
