difficulty starting when hot

[Steve101uk]

HI everyone

My fiat 2.3 multijet (2016) diesel starts first time with no accelerator every time, except when the engine is hot. If its been running and is hot, and left for 5-10 minutes I need to press the accelerator down fully to get the engine to start. This is never the case at any other time. It seems to be worse in this hot weather. Someone suggested it could be evaporation of diesel but I have no clue as I know nothing mechanical apart from put oil and diesel in. Is this something I need to get checked out? thanks in advance..cheers Steve

Could be the fuel pump or an injector(s). If you are happy to live with it as is carry on if it gets worse get it checked out.

Could be evaporation if it was pre-injection petrol, but not diesel .
Needs putting on a code reader with ability to scan real time graphs.
