[87T2swapped]

I have a 87 base shell i dropped a T2 motor into. I swapped the motor harness with all the senors and kept it pretty factory. Went to start it and all it would do is crank. the motor came from a running car but the shell wasn't. i have spark and i'm pretty sure on fuel because i can hear it going through the fuel rail and ive pulled off the upper intake and removed the injectors. all of them click. i'm at a loss bc it was running before pulled and started right up besides the rough idle issue it had. was said to have a problem boosting but was suppose to be a leak. ive checked my fuel lines and they seem to be hooked up right but it started up and ran on starting fuid for a moment so i'm presuming its a fuel issue. any ideas on what to check and where to start would be awesome. thank you
