So I just recently had to swap the whole clutch system in my 06 ss sc g85. It sat for a year cause I paid a friend to do the work since he's a mechanic and all he did was unplug a bunch of **** and take a tire off lol. Anyways aside from that drama, I ended up doing the work myself and got everything plugged back in right and hooked up. Drained the old fuel, trans fluid and oil, put all new fluids back in, put a new battery in and now when I try to Start it. It will Rev to 3k rpm like normal but then immediately dies. I hit the gas and it'll sometimes try to Rev a little, like a couple hundred rpm for less than a second and that's only sometimes.

The only two codes my u scan is bringing up are p0033 and p0443 so sc bypass valve control circuit and evap control circuit. But those shouldnt prevent it from at least running, maybe running rough but could they really cause it to just die like that? Fuel pump is priming and running. My air fuel gauge though is all over the place after it dies, don't know if that's a clue to anything.

I've found alot of stuff that can cause this online but it's not throwing codes for those sensors. Please any ideas would be awesome!
