Today while cleaning my car, after I moved it onto the driveway and turned it off, I heard my fuel pump continue to run (same sound as when you turn key to on postion). I started the car up again and it fired right away. Turned it off again and heard pump go again. I've listened for this sound before but I don't think it does this all the time. I will be sure to listen for it next time I drive the car and turn it off. Is the pump supposed to continue running after shutting car off? Could my hard start problem be the result of the pump not continuing to run after the car is turned off?

 

same thing happened to mine.....it was the oil pressure/fuel pump sending unit .....just my .02

 

so is it supposed to run after the car is turned off?

 

No, sounds like a bad relay.
