Alright everyone, I am having some issues with my DSM.

After finally figuring out that i plugged the Crank Position Sensor plug into the A/C connector causing the car not to start, i plugged it back into the right connector and the Car starts but refuses to stay running.

I just completed the AWD swap to my 2g GST, and for the life of me, i can't figure out why i am having issues with the car staying running. I didn't change anything engine wise, just a brand new flywheel, clutch, Pressure plate and starter (and of course the transmission)

The car will start, and after 2 seconds it'll choke itself off, if i feather the gas, it chokes and dies, but sometimes i can rev it to 3000 rpms (which i shouldn't do on cold start) and it'll try to die and choke out, but i can feather it to stay up.. but will die moments later.

I am running e85, 255 fuel pump, HX40 turbo, and on speed density. I put new e85 in (about 5 gallons) and my fuel pressure regulator is saying i have fuel pressure.

What do you guys all think?

It sounds similar to a problem I had when I switched from 660 to 1450 injectors. Check your global and deadtime, and you can probably try increasing them until it can stay running and then fine tune them after the car warms up a bit. After a couple of no starts you might want to wait a few minutes to prevent flooding the engine.
