Cold Start Control Pressure is too high - adjust the WUR. You could also test this theory by [while cold]:
1. remove the air filter housing and expose the metering plate
2. have someone else try to start the car [with no gas pedal]
3. while the starter is turning, you push slightly on the metering plate [just slightly - maybe an 1/8"- 1/4"]. This will cause extra fuel to go into the the combustion chamber and should help the car to start immediately.
4. If this works, then you'll know your car is starving for fuel...

This would be a problem with your WUR. You'll need CIS gauges to test and see if your cold control pressure is within spec. If it is in spec, then your Cold Start Injector may be inoperable...
