cold start problems

When I start my car after it sits for a ling time, it doesn't want to start or idle. After the engine is over 120 degrees, it runs great. When it is already warm and i try to start it, it won't start the first try, but it starts right up on the second try. Anybody else with superram having this problem? I have a custom FastChip. What can i do to help with this starting problem.(I am sick of having to let my fuel injected car warm up for 5 minutes before driving)

It may be your aftermarket chip. Try putting your stock one in just to see if that fix’s the start problem.

Check for vacuum leaks. Set your minimum idle air. Calibrate your TPS sensor. Check your fuel pressure. Check your coolant temp sensor with an ohmmeter to see if it is reading within the range it should be.
