Hello,

I just swap a stock b20b3 engine into ek 97`..

So, i have spark at spark plugs, fuel pump working, have fuel at fuel rail.. Main relay click two times ( fuel pump prime ) and when trying to start main relay clicks one more, so three times click main relay.. Have battery voltage at injectors connectors and same at ecu side.. Just injectors wont work! I dont get any engine codes. This is stock ecu from b20b3, when I put a p28 ecu whit some basemap ( i think it is P72 basemap ) a car start immediately and runs.. A basemap is very bad ( it is very lean, like 15.5 -16 afr at any rpms, engine load.. )..

I swap a B20 engine harness into ek harness.. plug and play.. Can be connector for injectors harness..? I look that big connector, looks like same to b16 connector on engine harness..
I change a injectors, same problem..


What can be a problem ?

Can be ICM ? does icm control a injectors ?

Bad Main relay ?

Bad ecu ? How to test ecu..?


Any advice ?

Thanks,
