I tried to start my car last night and it didn't want to. I first tried and held it for about 7-8 seconds and let go. Then I took the key out, put it back in, cranked it again for about 9-10 seconds and it started then immediately died. Third time took about 10+ sec and me tapping on the gas when I heard her fire up to idle. I have NEVER had this problem b4 and had 1/2 a tank of day old 93 octane. It scared the hell out of me. Anyone know what could be wrong?
