<human>:  My car won't start. Can you help me troubleshoot the issue?
<bot>: The first step is to make sure there is fuel in the tank and that it is reaching the engine. Check the fuel filter and fuel pump to make sure they are in good working order. If that is all in order, you may want to check the battery or alternator for any issues that may be preventing your car from starting. Finally, you may need to take a closer look at the spark plugs to see if they are in the correct order or need to be changed.
