 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 ?

 Person2:  So what do you think it is ? 
 Person1:      I know this may seem like a silly question , but does your car have gasoline ?
