hi i have a version 3 wrx 97 when its cold it goes to start then dies (most of the time) when its warm it starts fine. ive been told crank sensor or coolant sensor are the most likely causes. if it was a crank sensor surely it would not crank at all? or is that not the case?? I have alreadyhad it at a garage once and it decided to start and they decided to tell me there was absolutely nothing wrong with my car as he said no error coeds came up... please somebody advise me as its starting to p*ss me off now.

Cheers
Lee

 

coolant temp sensor would be my guess.
I had cold start/running problems ,no error codes got it changed sorted the problem.

 

as above.

 

mine does exactly the same so would be interested to know the result im going for a temp sensor.. but mine has lots of black smoke on start up and seems like it fouling the plugs too..

 

ahh black smoke dont sound to good i get no smoke, guna try changing both the sensors c if it works. cheers guys.
