Sounds like a faulty temp sensor to me look's like it's showing a warm engine reading so the ecu will not put enough fuel in for a cold start. I think the sensor has 4 wires to it and is in the top of the thermostat using. These can cause all sorts of problems on cars in general
That again, is some sound reasoning - thank you scooterman.
Being baffled by the under-bonnet array of original fitments, I'll need a routemap to where the 'temp sensor' of which you speak is located - I seem to remember a photo on this site with all the components listed? I'll search in the morning.
But, your diagnosis does collate with previous 'refuse-to-start' scenarios that I have encountered this winter, where on recent cold-and-frosty mornings, Alfa would play dead - and yet, in the afternoon would spark up, like nothing ever happened.
And then you reckon, replace temp sensor with a new one and Dead Alfa springs to life!
Greets to all...This site keeps my Alfa on the road.
