2002 Turbo Camaro won't start when hot, especially if it sits and idles for an extended period of time. It just seems like the injectors don't pulse when cranking. I can spray carb cleaner in the throttle body and it fires up and then stays running. The car starts great when cold, just doesn't like to start cold. I've played with fueling while cranking with no help.

I have read about moving the IAT sensor helps but that is tough to do when you want the IAT sensor after the methanol injection nozzles.

Does anyone have any recommendation to help this? I have experienced this issue on 3 different turbo cars but this one is the worse. The others would start hot but they would crank a fair amount before finally starting.

How about some info on the system?
Same tuner on all 3, I assume.
Maybe, post the tune and a data log or two.

Yes same tuner, I have tuned all 3 of these cars. I don't have a log from the car. I can work on getting a log when it won't start. What specific parameters logged would you like to see?

Injectors are FID 1200.

If you haven't messed with them, go look at the Idle \ Startup section.
