1995 sc400 with 1993 engine problems

I have a 1995 SC400. Just got done installing engine from a 1993. It will crank but not start on its own. It will start with starting fluid spray and run but only while spraying it in. If the throttle is held wide open it will run for a second but extremely rough. I have done a fuel pressure test and it's pumping just fine.
Today I put in an ecu out of a 1993 but exact same result. Any advice?

Check coils and connectors onto the coils. Had the motor been sitting? Injectors are prone to getting sticky. Tap them gently generally gets them going. Check for air leaks.

Update: installed the injectors from the original engine did the trick. 7 of the 8 on the used engine were stuck closed. Thanks for the help!
