Three things determine the start of a car

1. Starting system, if you can hear the "噠噠噠噠響聲" and the sound is similar to when it is in normal start, your battery is good and your startor is good.

2. Fuel system, turn your car key to on position (not the starting position, when key on "on position", all the lights on the instrumentation panel will light up, if the AC in turned on, your cooling fans will turning), with radio, AC off, if you can hear a slightly muffled motor sounds at the first 2 seconds (fairly weak, from the back of the car), you fuel system is good.

3. Ignition system, including spark plugs, wires, and distributor (new car are electronic, but the same principle). Testing this need some tools, if you know how to test a spark when starting the car, you can easily know if your ignation system works or not. Spark tester cost about $10 in most of the auto parks store.
