car struggling to start from cold-keeps turning over then fires up with smoke
my car has just started to struggle to start when cold ie 1st thing in the morning or when i leave work and its been sat for 10 hours
the car keeps turning over and over for maybe 10 seconds or so then fires up but gives out like a grey/white smoke as soon as its fires then its fine,doesnt smoke when on idle/under load etc
its has done this 2/3 times in the last week or so
all the other times it fires with the very 1st flick of the key.no back firing when driven or stalling at junctions etc
any ideas?

Do you leave the ignition on for a second or two before cranking the engine. If not its worth trying to allow the fuel pressure to fully build up before cranking

When my crank sensor went it would not start 1 in about 15 starts no smoke when it did it would just crank endlesly. You would give it a minute and would start within 2 seconds. So doubful its that.

Mines done this and when it did i would notice the ignition advance would reset on my data monitor as well, cleaned the crank and cam sensors and its been fine since, it would sometimes throw a cam sensor code up, even though it would not show the management light 
but the code was normally present when I checked for previously stored codes, and I would always wipe the codes after each time to see if it done the same, and every time it didn't start it would normally throw a code of some sort, but not always!

Have you cleaned the cam sensor, mine was on the right bank, like I say that's the code it would throw when it done it to me, cleaned it and was right since, ain't used the car in a while now tho so may still happen when it's back out
