my girlfriends 99 civic 4 dr EX operates/runs fine and smooth, however, when she starts up her car and her gas is pretty low to empty(1/8 quarter to the bottom and lower), she has a hard time starting up, like it chugs 2-5 seconds b4 it starts, it always seems like it will start up but takes forever to actually start. now i know when ur car is low on gas some people have told me its hard to start up a car, but i think its weird this happens, ive been an owner of a camry and new 98-02 model accord, and never had this problem, and ive been below empty many times and never had a problem starting a car. she just recently changed her battery cuz her mechanic said she needed to(who knows if she had to?), she does need to change her spark plugs(according to the manual), could there be a particular reason this happens? is it normal, and am i just lucky my cars dont do this, i know a simple solution, fill the gas up b4 close to empty cuz its bad anyway, but im just wondering if she has a bad part or something else clogged relating to fuel or something that could lead to other problems. sorry, and thxs guys.
