It does look like a leak type situation. If you open the hood, and start it in the morning, if there is a leak, you should smell gas.

Also check the cold start valve. You can remove this valve from the engine and see if there is fuel coming out when you crank, there should be a spray.

If you dont see a spray:
you can check the voltage at the cold start valve's connector. You should get about 10-11V when you try to start the car.
If you do get this voltage:
then check the resistance across the cold start valve's pins (connector removed). It should be between 10-20 ohms. If you dont have resistance, replace valve
If you dont get this voltage:
then there is an electrical problem somewhere else.
If all electrical tests are normal but you dont see a spray, replace valve.
