As the engine cranks , the ECU should be enriching the injectors so it fires up quickly then the ISCV takes over to idle the machine.

So when turning on the key does the fuel pump prime (any noises?)  and if you cranked , does it spark ?

if you’re sure the harness is spotless , we could check the Clutch Switch , Neutral Switch and Stand Switch, these definitely also cut the injector and sparks off.

If not, keep an eye out for a backup ECU you could get
