I have a 2004 Toyota Tazz and very occasionally the engine won't start. It'll turn over and sound like it's starting, but won't start. Then I'll try again and it will start fine. This has probably happened twice in the past 6 months. I always just took for granted that sometimes starting doesn't work and never really thought otherwise, but today it happened again and I realized that what I was taking as normal may be an actual problem. My car gets serviced regularly and doesn't have any other major issues. Apart from being 12 years old.
So is it reasonable for a (old!) car to not start the first try on occasion and still be considered fine? Or is there something wrong with my car?
