Person1: Hold on , before you kick your car let ' s go through some possible problems .
Person2: Fine .
Person1: OK , first of all , can you turn the key in the ignition ?
Person2: Yeah ! I am here with my friend and he thinks it may be the spark plug or the starter motor .
Person1: Those are possible problems , but tell me , when you turn the key , do you hear the starter motor crank ?
Person2: Yeah , it sounds like it usually does when I start the car , but nothing else happens . The engine won ' t start . Should I maybe press the accelerator ?
Person1: No . If you step on the accelerator pedal you can flood the carburetor and your car will never start .
Person2: So what do you think it is ?
Person1: I know this may seem like a silly question , but does your car have gasoline ?
Person2: Umm . yeah ! Right ! I got the car started ! Thanks for your help ! I told you to fill the tank !
