F20b swap my 1992 prelude won’t start

So I swapped an F20b into my 92 prelude and it won’t start. None of the injectors have any power. Haven’t checked spark. I swapped all the OBD1 stuff onto this motor. So it’s conpletely OBd1. But still won’t start. Any help please

P28 ecu with F20b chip. Dash harness is a h23. Everything else is from the H22

What injectors are you using? Did you retain the resistor box?

Obd1 Injectors from the h22. And yes resistor box is still there. I also have no spark either

Re: F20b swap my 1992 prelude won’t start

If you have no spark and no injector pulse, it sounds like you may possibly have a disconnected engine harness plug. It could be a bad ECU also. Can you verify that the ECU works? Does the CEL stay lit when you put the key in the "run" position?
