Zafira 1.8 petrol auto 2003 - Cold start problem - please help !! - MarkyB
Recently bought a used car, noticed at the garage that the idle was very lumpy and the rad was leaking but other than that seemed ok, got it home and about a week later a problem has risen its very ugly and frustrating head !! The first start of the day when cold is really hard, almost to the point of killing the battery cranking it over!

When turning the key it cranks over but does not seem to want to fire, eventually it does but only just !

Had a new radiator fitted first to cure the leak although I know this is nothing to do with this issue, just trying to give all the history I know

Thought maybe it was it not getting enough air, so the air intakee valve was stripped and cleaned and replaced with a new air filter at that point

Still didn't seem to want to fire, so full set of new plugs were put in, coil pack has been replaced also

Oil filter and oil changed

Checked fuel pressure, the rail is primed and there is loads of fuel pressure so didn't appear to be a fuel supply issue

Took it to a garage, had diagnostics done, ecu reported a faulty crank shaft sensor, replaced this, made no difference (although it has cured the rough idle when it is running)

Battery is good, in fact cranked it over with battery attached to a second huge battery at same time and still same issue, so don't think it can be any issue there!

At a loss as to what to try next ?? Can anyone advise ?
