i have this problem for a long time. everytime i have to crank it 2 to 3 times before it start. everytime you crank it and it doesnt start you could see a white smoke coming from the airflow meter, and you could smell gas. i already change the airflow meter, did a tune up, change the OVP, FP relay, engine temp. sensor, cold start sensor, fuel injector. i have been to 3 different garages and they keep changing parts thats doesnt fix the problem. i have been to different forums and nobody seems to know the culprit.
