Start stall

Runs when gas is sprayed into the intake so far codes that have popped up are 14 15 33 and 43. We don't really have vacuum lines hooked up reliably but would appreciate someone who knows what they're talking about to chat!

I'm not sure what "don't really have vacuum lines hooked up reliably" means. Vacuum lines and their correct routing might be important.

Code 14:Coolant Temp Sensor - High Temp Indicated > Tested the CTS?
Code 15:Coolant Temp Sensor - Low Temp Indicated > Tested the CTS?
Code 33: MAP/MAF Sensor - High Voltage/Low Vacuum > Tested MAP/MAF Sensor is showing correct voltage w/ Key On Engine Off?
Code 43: ESC Low Voltage?

This is all I can offer, I hope that "someone who knows what they're talking about" chimes in!... Like Tuned P The Great lol!
