okay so i got in my car today and it started. i was in my driveway slightly on a hill. (the front facing downward) last time i tried to start it i was on flat ground. my gas said it was at quarter tank. i topped her off today. but its been starting before that. before i put gas, i tried to start it and it started right away then died right away. it did that twice. then after that i started it about 10 more times and it fired up well. may it be that my fuel guage may be broken? and should i keep it always about more than half tank fuel??? get back to me please im becoming confused.
