Starting problems

[izzysnan]

Hi guys
I'm looking for advice on a starting problem - my 850 T5 estate starts first time when the engine is cold but won't start once it has warmed up. The Volvo dealer suspects the front oxygen sensor which is expensive & I don't want to go down that route if it could be something else (cheaper). My starter motor is on it's way out too but I suspect that either air or fuel must be the problem as it starts so easily when cold.
Any ideas please?
Frank
By the way it also runs fine once it starts.

O2 sensors aren't expensive, Salvo will have one for about £25 odd don't forget the discount via this site, or Euro car parts do them for about £70 new i think.

Thanks for the info - much cheaper than the dealer quoted.
But is it likely to be the O2 sensor?
