    Should Fuel Pump Be Constant

    I was having trouble starting my car and decided to check my fuel pump and noticed that it seems to be pushing petrol through intermitant, should this be the case or should it be pushing it through constant.

    Fuel pump should run for about 3 seconds when you first switch the ignition on then stop. It should then start again when you crank the engine over and obvioulsy when it's started. If it fails to start or stalls it will run for about 3 seconds again and stop

    sometimes you can hear it start for three seconds other times not.
    but when its feeding petrol through it seems as though its pumping it through intermitant. is that normal

    If your constantly switching the ignition on and off sometimes it won't pulse for the 3 seconds

    I can only comment on the electrical side of things though
