iq engine swap

[Setenta]

Hi everyone. I swapped my engine for an identical one. Once I put everything back and start the beast there is no fuel coming up to the injectors. Also when I get all the lights on in the dashboard I don't hear that noise when fuel pump gets ready just before you start engine. Any of you guys know what to do now!? Thanks

Just a wild guests here, but I've heard with some cars if you change a component for example an electric window motor, then the car has to be hooked up to the diagnostic machine and told it has a new motor fitted. The same with my wives Grande Punto, when it had a new power steering column fitted, it had to be hooked up to get it calibrated.

So I'm just wondering If the same applies here?

Have you used the cars original ECU? Does it recognise the injectors/throttle body?

Like I say just guessing/thinking out loud.
