i have a 2003 si and its worked fine the whole week but this friday i drove it thursday nite and everything was fine. I got in it to go to work on friday and when i started it it sounded grogy and exaust was a little louder then normal and it just died. tried to start it again and it was loud rpms went up a little and the it died again then i could smell gas. im thinking it might be my fuel pump cause i can drive it around the parking lot but its lack of power then it dies so i parked it. please help. note i have a check engine light on but its been on bc of a 02 sensor and that shouldnt cause my car to die aka shut off.

 

did you check it to make sure there are no other CEL's

 

it could be possible you have another cel too...
