Here's what it sounds like to me. your cold start valve is working, firing a nice shot of fuel into the intake, to get it started..............but your engine uses up that fuel and the engine dies because your fuel pump may not be working. A simple check to see if the fuel pump is working , as Chris says, is to remove the air filter and lift the air plate. Do your injectors squeal as they get pressurized? If so, your fuel pump is working. i would try this simple test 1st....sometimes, after having the engine out, the fuel lines are totally empty and need to be primed a bit to get things firing. If you find out that the fuel pump is working, the system is primed, the injectors are squealing, etc. and the car still won't continue to run.............I'd move on the system pressure tests.
