850r running issues

[Liam850r]

Hi all please help my 850r won't start when it's hot just turns over but nothing starts if you give it a push no problem! Other thing not sure if its related lambda sensor warning light is on and I don't have full boost :( very unhappy! Any advice greatly received Thanks

If your running a mapped ecu try a stanard one sounds like my old mapped ecu perfect when cold very very hard to start when to the point where there was fuel comming out the exhaust lol

Has anybody else had start up problems when engine is hot so many different suggestions on the web don't know what to change first, it still doing it with ecu change :(

Coil pack and ignition module?
