there's a service bulliten from GM regarding carbon build-up you want to look into.

How is the fuel filter and fuel pressure?
Time to get a fuel pressure gauge on it on the cold startup.
Check for pressure up to specs.
If it is not the injectors will not squirt fuel on a cold start.
You have got to have the full fuel pressure.
Do not leave home without it.
Post back fuel pressure with eng sise and engine code
