spark, fuel, not firing

right now it has nothing to do with the computer, i just need it to run. it ran on the pt3 before i got the p13. then i wired in my VAFC in backwords, i looked at the female ends of the ecu connectors and not the side with the wires. i then wired everything up correctly, and it didnt start after that with the pt3. i got a code 15 which is ignition output signal. i changed the ignition module and still doesnt fire. any ideas?
