Hi all - my Ford Focus has a bit of a glitch with starting first
thing in morning ...
It fires first time when key is turned but then cuts out immediately -
second turn of ignition starts ok when revved ....
This only happens after standing overnight otherwise ticking over and
running well and starts first time during day .
Have changed plugs and HT leads so don't think it is any thing with
dampness etc.
Any ideas anyone ?
Thanks for any help

Perhaps its losing fuel pressure in the line from the pump overnight?

Genuine plugs and leads? Plugs gapped to 1mm, rather that the 1.3mm they
are sometimes supplied with?

thinking about this, don't car have electric fuel pumps in the tank
these days ? Perhaps air gets in the line ?

Thanks for replies - my thinking is towards fuel related
It fires first time but you need to rev engine straight away or it
dies......
There is a hissing noise from left rear of engine ( looking from front
) so could be something to do with a vacuem leak in hose possibly ?
Anyone experienced this ?

there should not be a hiss. some fords have vacuum operated heater flaps,
any leak in those will give a hiss and yes that could well cause your
starting fault.

But not the Focus, AFAIK.

if there is a vacuum leak it might cause an audible hiss, if so it will
probably be remote from the engine (or it would stop instantly) so have a
good look for any vacuum pipes off the inlet manifold, there is usually one
that goes to a bit of gubbins on the firewall at the back of the engine bay

I have read all the replies. I did not see Idle Control Valve
suggested so I will throw it in the mix. I seem to recall similar
symptoms on my Focus 1.8LX, culminating months later in not being able
to idle at all.

HTH,

Nobody mentioned it because it didn't fit those particular symptoms i.e.
starts then cuts out then starts again and is fine for the rest of the
day.
