Nissan Repair: nissan primera 20 slx auto cold starting, nissan primera, cold start

Question
I have 1994 primera 20 slx auto it will start up and run but then after 30 seconds will cut out.  

Answer
It sounds like the cold start sensor is not reading correctly and the car never goes into cold start mode.  After it warms up I assume it runs fine?  Anyway, if this is the case go down to Nissan and purchase the cold start temperature sensor and replace it and you should be fine.
