I have a similar intermittent cold start problem with my 1.8K EU3. Fully charged battery, engine fires immediately first time but then dies - feels like it's being choked/over fuelled. I can sometimes keep it running through heavy use of the throttle pedal and sometimes it will settle to a normal idle, but on other occasions it just seems to keep over-fuelling and the engine dies. When it does die, an immediate restart results in the engine idling normally! I'm guessing its either a sensor (IVAC?) issue or possible injector wear (26000 miles), but would welcome thoughts from those that have experienced and fixed similar issues. On the K click - this normally occurs (but not always!) when the engine is hotter than usual (somewhere in my mind I remember my physics teacher making a correlation between electromagnetic fields around wires and increased electrical resistance when heat is applied!). Wires to the starter are heat shielded from exhaust heat with reflective tape and when it happens I can normally lift the bonnet and wiggle some wires to get it going again. I thought there was a guide somewhere on here on doing the relay mod - can someone point me to where it is please? Bob
