Coming from vacation after 5 days my civic 99 DX won't start. When I try it cranks for while but no luck. So I took the battery to checker they told battery needs to replace. I changed the battery. Still no luck.

Could anybody please suggest what I need to do next? I know very little about car so if you could be descriptive I would appreciate it. I gues I could have it towed to mechanic. But you know if I can do something myself...

Read sections A and B below, if you have a "crank but won't start situation:"
