moto keeway 125 tx efi doesn't start anymore

[tica 13]

Hello friends, does anyone know how to repair a Keeway 125 tx enduro efi, 2021, which after a period of inactivity, did not want to start, it has petrol, the spark plug works, the injector works when it is fed directly, even after the direct feeding of the injector by injecting some gasoline, the engine started and worked for a while while there was gasoline in the intake manifold, I mention that I changed the ecu with a new similar one, the obd tester recognized both, nothing changed. Thank you

Does it have an immobiliser? Many ecus are programmed to the bike so changing the ecu means also changing the chips in the ignition barrel and key. 

 

Or some can be reprogrammed to the bike but you need the kit to do that. 

 

A lot now immobilisers cut off the fuel supply which sounds like what you are describing.

Thanks for the advice, the fuel pump works, it doesn't have a sensor for the ignition key. It does the same with both ECUs.I am attaching the electrical diagram and ecu, maybe there is an ideaYeson 28S Manual.pdf

I don't know how it works and I don't have the electrical diagram of BULGLAR ALARM
