What was the ambient temp when you tried your last cold start? It may be possible that your cold start injector is defective and/or there may be a fault in the plug or wiring going to it.

Ya Shelby?
it is more then likely the cold start injector, if your car has one.
You have not told us what your car is or put it in your signature.

The other possibility is the thermo time switch
Also check the aux air valve for not opening enough - pull the front hose off it, and check that when cold, you can get at least a pencil right through.

We need as much detail as possible
