Non start when car is cold and it's wet

[fraz101]

Any common problems for non starting first thing in the morning when the weather is wet? Once it's started it's fine and if the weather is dry it also starts no problem.... Have replaaced tdc sensor and connector to no avail... i'm thinking the plug leads might be arcing out in the damp?

Make sure the under bonnet fuse/relay box isn't 'water cooled' or has corroded terminals, an ill fitted top section normally channels water in there.
