2.8 v6 to 5.0 tpi no spark or fuel
Just swapped in a 5.0tpi into my 2.8inj firebird,both 1989 (i think),swapped the engine loom and the computer,engine turns over,fuel pump primes but no spark or fuel?Not 100% sure they are the same year maybe 1989 or 1988.

Check for loose/crimpped wires at the dizzy make sure it hooked up in right spot check fuel pump fuse its located behind headlight its a 2 wire black single fuse holder with red/orange wires if i rember correctly could also be an issue with your vats (security)
