Hi all, long time no see
So im currently having an issue on my wife's Bravo 07 1.4 T-Jet. (lovely motor)
Car won't start some times.. From second try engine fires.
Starter motor spins engine as normal.. And the battery is oldish and much bigger then suppose to be.
But again engine spins, but won't fire..
Done all the service + spark plugs.
No warning lights, no codes.
Could it be battery? But then again it spins engine as normal.
Ignition barrel?
Need ideas where to check now.
Sometimes everything ok, but other times from second or third time engine starts.
Any help/ advise welcome.

Simple and may be daft but is the throttle body clean. MAP sensor may also need a clean?? Then maybe temperature sensor. MES might identify something.

First - put fresh petrol from petrol station and watch if this happen with it.
Second - rotate the key to MAR position then OFF then again to MAR then OFF and then start motor. Can be the low pressure from petrol pump.
