s2 cold start problems - advice needed
hi, as some of you may have read, for the last few days i have had a start-up problem on my s2.
in the morning, when i try to fire her up, she starts for a nano secont, then just cranks over....
there is no fuel at the injectors, unless i hold the flap slightly open on the metering unit, then she will splutter and backfire for a minute, cutting out or really struggleing to idle. then she will all of a sudden clear up, and all is ok
yesterday stu said he was 100% it was an air leak, but then it was fine so i didnt look... this morning it wouldnt start again, so i will check that now.
why would an air leak cause these symptons? any other suggestions?
any help mucho appreciated

Ive got very simmilar problems, i thot it was because my car doesnt get used often, but when it does get used it's the same not even when its in the morning, but if its started, left to cool down for a few hours and then it's the same im pretty sure i dont have an air leak aswell

Is it possible to tell if their is an air leak by the vacume on your boost guage? 
And when my car is running, if I lift the oil cap it sucks it back on, so their must be good vacume - but again will this show if i have a leak?
Car starts if you leave fuel pump priming (bridged relay), press the flap down once, or if cranking and someone holds flap down bout 5mm
runs dog rough when cold, try and rev and it'll cut out, after a minute it's perfect!
And do S1's have the heated seat fuse?
im off to check for that fuse!!!
