Technical My stilo doesn't like the mornings

[Juelz]

My stilo is difficult to start in the mornings.

At first, I put this down to worn out spark plugs and the car needing a service as it was approaching 72,000 miles. I've had it serviced now, and although the starting has got better, it's still a bit reluctant to start in the mornings.

It doesn't seem to make any difference whether it's a warm morning (like recently) or a cold one, which makes me think it's not battery related.

Any ideas?

Well, what's wrong with the starting?
Does it turn over slowly, misfire, not fire at all then suddenly start
Bit more info please

Slowly.

Somemes it doesn't fire at all, then starts straight away after that.
Always starts easily when the engines warm as well.

The fact it turns slowly means battery, earth line or starter. So, cheapest first

EARTH CHECKS
Check your earth line. put a voltmeter between the battery earth and a good earth on the engine. engine on and load up the alternator with some electrical load, should read 0volts or damned near, showing very low resistance

BATTERY
HOLDING VOLTAGE
see what volts it holds after an overnight stop.
CRANKING VOLTAGE
Check your voltage across the battery whilst cranking the engine

95% of the time it will be one of the above. If they're both ok then you need to move on to checking the starter
