FH12 500 cant start

Hello

Trouble with FH12 D12d 500hp engine crank but not start, try to put just a little bit petro into intake manifold and engine start and running good. once shut the engine off, have to repeat again even the engine temperature at around 75 deg C.

Injector issue or what i have to check with Vcads, fuel feed pressure, boost pressure and there is no fault codes for engine.

izzit call flame start???

Thanks.

run fuel consumption test on idle
at idle in must be 1.0-2.0 l/hour

If you cant start engine without petrol it will be 99% that unit injectors nead to replase. Sometimes with vcads you can see fuel consumption 2l/h and it looks normal but engine wont start and if there no stored fault codes MID128 SID21 or SID22 just replace injectors
