Are you using the wiring harness for the 96? I swapped a 95 motor in a 94 bodyand used the 95 harness and same problem your having. Put the 94 harness on the 95 motor and worked.
If your using the 94 engine harness you will need to re-pin some connections.

Schematics in there. Also in the Conversion section.

well we got that problem figured out, now we have a new one, the car fires right up like it should but 1 circuit of injectors (1, 4, 6, and 7) will not fire...
we used the 94 pcm and engine harness and left the "in the car harness" the original 96. the spark and fuel problem was a wire for the pcm that was pinned different between the 2 harnesses.
HELP please!!

go to wires going into the pcm, you should see a small orange wire, that is the power for your pcm, make sure that wire is getting power, if its not that will cause no fuel pump, no spark and no injectors, and also your check engine light wont come on, if its not getting power try to switch pins around, with a digram from aldata or something like that, or you could run a wire with a fuseable link from the bat to the orange wire and it should start,

No **** their different or you wouldn't be here. You need to move the wires in the connectors to get things lined up. If you can't figure it out from those connector pinouts then find someone that will come and do it. Or change the engine harness to the same year as the body but then you will run into the opti plug being different vented/non vented.
