No start after injector swap?

[19Cutlass94]

Hey guys, I just swapped out the Multec 1 for Multec 2 injectors. The Multec 2 harness I had, I used the injector connectors on my old harness. I matched up the connectors, wire for wire ( which was easy because GM used difference colored wire for each plug ) and those matched between the two harnesses. I soldered every connection then heat shrinked it, I put everything back together, and now I have a no start condition. Ive tried several BIN's and all do the same thing.

The SES light doesnt go off with ignition on. and check gauges light doesnt go off either.

What could have gotten messed up to the point where its now like this?

so it cranks and doesn't hook at all? do you hear the fuel pump hum at key on? do you have pressure at the schraider valve on the fuel rail?

I found thr problem. Injectors were junk.
