Mazda 2 - Won't start from hot - Leon64

Hi, any suggestions as to why a Mazda 2 diesel (54) would turn over but not start when warm? Seems to be getting worse.
Many thanks

Have you had it scanned?

I'd be interested in the live data fuel rail pressure.

This will be running the Ford/Psa diesel engine,so as suggested above,fuel pressure when hot is key.

If it uses the same HP pump as the PSA engine there could be a pressure regulator on the back, these can cause that problem on the C5.
