If your coolant temp sensor is bad the ECU will still check for it before the car is started even if you unplug it. Because if the weather is cold, it will go to the cold start enrichment map in the ECU to help with cold weather starting. Disconnecting it will not do anything because the ECU will still see it as a bad sensor. So the ECU still won't switch over the correct map for that temp.
If you can get it started your car should run like shit and will hardly idle until the CEL comes on and then it will switch to a different map and then it should idle fine. But getting it started will be the hard part.
Talk to Jet and see what he finds out with his car. His Talon is doing the exact same thing and it might be a combination of the FPR or one of the three or four coolant temp sensors.
If your car is running ok after you get it started and its not misfiring. I would doubt that it would be injectors or bad gas, since if it were you would have re-occuring problems after startup and they would show up in normal driving as well.
