I dont use my zed very often now but if i leave it say a week or longer it doesnt start staight away takes like 5 to 10 seconds and smokes a bit misses a bit then fine after that doesnt smoke on idle and starts fine durring the day and next morning .just when left for long periods it does this does anyone know what it is or is this ok thanks taff.:yes:

when was the last full service on it?

Could be the fuel pressure regulator letting the petrol back into the tank when its been standing a while, id change that first as they are relatively cheap compared to what it could be, which is a leaky injector.

 

What colour smoke is it in start? as valve stem seals can leak, causing blueish smoke on start up. especially if it then clears.

i had a similar probem a few weeks ago, turned out to be one of the fuel rail pipes had a tiny hole in it, so when left it was de pressuirzing, and taking that bit longer to start.

 

i had a small amount of black smoke once it did start.

 

new pipe and was all solved. could be worth a check if you cheching the regulator too.
