So i have been having various different problems with my Z. When i try and start the car it just dies out at the first turn of the key when i try again you can hear the motor begin to turn but then it dies shortly after once i turn they key for a 3rd or 4th time it then starts. This has been going on for a few days. Today when i started my car and went to run an errand i noticed the temp was rising so when i got home i went to check my radiator. My radiator cap has a safety pressure release on it so i pulled the lever up and all of a sudden my radiator sounded like it was flushing out. It sounded like that for awhile and then i noticed smoke coming from right above where my drivers side headlight is at. I was wondering if anyone has ever had a similar or knows what might be wrong with my car?
