Hey so my sc has stock ecu, stock 330cc injectors, stock maf, I have a ffim installed so that's the reason I don't have my iacv connected, everything else is connected.. Does the iacv affect this?

I think the IACV would effect it in some way, but than again, it could be a whole other issue.

why would you disconnect it from the get go? Idle erratic or something?

I disconnected it because of the Front facing intake manifold. I dont have a flange on the manifold for a Iacv.. Wish theres a way i can test if this is my problem

Try pumping the throttle while your starting it and then open it approximately 20-30% and hold it there till it will idle on it's own. Your throttle body also needs to be slightly cracked using a set screw at idle due to no IAC valve to stay open and control it.

Also try plugging in just the IAC by itself, maybe the stock ecu detects it not being there and isn't allowing it to start. Is the timing synced properly?
