Hello Michael,
Can you be a bit more specific ? If it fires and stalls 12-15 times before running, it is probably not the CSV. It is also probably not the WUR connection. If it fire and stalls, the CSV is working, but the initial mixture is too lean to make the transition to cold running. On CIS lambda, there are a few tests you should do. First make sure the relay is working and the system pulses the FV at the cold default value. Check the temperature switch on the right chain case. If OK, disconnect and plug the grey hose behind the distributor, start the engine and check the ignition timing and the FV duty cycle.
