2001 VX Berlina, generally starts up instantly from cold, but on hot starts it will fire up, run a couple of seconds then die. Will do the same second or third time, after that it fires up and runs fine. No other issues, idles fine, no missing even on full throttle (which I do probably more than I should) Ocassionally it will do the same on a cold start, take four or five tries to get going, but most times its fine. Sometimes it starts from hot first time as well. No unusual dash lights appearing.
Have tried changing fuel filter (it was due anyway) no joy. Throttle body was cleaned a few months back, leads and plugs changed as well (WAY overdue, they'd done 140 thousand km). Have checked all vacuum pipes, cleaned MAF sensor. Fuel pump was changed about 3-4 years ago, issue didnt really appear regularly until last year. Have some injector cleaner, worth trying?
Am thinking this may be a tired fuel pressure regulator, car has done 340km. Searching threads here also suggests purge valve as a possible culprit
