i have a 2003 Honda civic lx 4 door automatic. ive had it for 2 weeks now. the problem is every time i drive somewhere and have the car turned off for 10 mins, like lets say i go do groceries, the car doesnt turn on right away, have to crank it for a good couple times before it finally turns on. last night i went to a friends house went in for 20 mins or so went to leave same thing and then the car turned on but would shut off right after. i dont know whats goin on. when i let the car sit over night it cranks right over. help!! any ideas what it could be? fuel pump? distributor?
