Was the car running prior to safc install?? Sounds like distributor is off a tooth or possibly 180..

The only wire you should of cut was the mafs wire, which if it's cut the car would still start... everything else should of just been tapped into for signal...

What exactly is your setup? Injectors, fuel rail, fuel pump etc. It'll help troubleshoot.

right now sc, 370 injectors stock pump and ecu with safc 2 rb20 side mount intercooler custom plenum getting rid of itbs for now and putting the stock throttle body back in the intake side of the sc i know its not the best but thats all the funds will allow for now

i need to post pics of the final product but i dont have any right now but as it stands right now i have the supercharger under then mani and itbs with a plenum put the iacv and the aac valves on the plenum and wired everything as normal minus the throttle position sensor i spliced them together using the stock plug and the suzuki sensor when i got the safc2 wired in and did the sensor check and monitor mode the throttle was at a steady 20 percent and wouldnt come down even after i adjusted it but i didnt think that would affect it from starting i did crank on it alot trying different things could it have jumped timing
